Ashes to Ashes

''Fame: puts you there where things are hollow'

It is something of a shame that the man who, even while assiduously courting it, regarded celebrity with a certain amused cynicism - "I'm an instant star. Just add water and stir" -  could not enjoy what has turned out to be a mass media hagiography of epic proportions (unless, of course, we have just collectively witnessed the pinnacle of a career dedicated to performance art; think of that 'Lazarus' video...).

While it was reasonable to recognise in a news broadcast the importance of his influence on popular culture, Radio 4's Today Programme went so far overboard it ended up effectively scraping the bottom of the ocean. A veritable host of callers popped up to describe even the most fleeting interactions with the star, while the programme itself turned into a rather trendier version of housewife's choice as enough exerpts from his records were played to make the copyright owners very happy indeed.

As the day wore on, endless interviewees from the music industry queued up to explain in lavish detail what Bowie meant to them personally and - more importantly - how he influenced their work. You can't blame them, I suppose; as always, behind each banal celebrity is a ruthless agent demanding that the client somehow shoehorn in a reference to his or her own latest opus.

As a culture, we seem to be experiencing some difficulties in adopting a suitable degree of response to the death of a well-known public figure. While the Victorians admittedly threw themselves into the whole business of mass mourning with unaccountable enthusiasm, the British attitude in general has traditionally been one of restraint - possibly because there were usually more important things to worry about like civil war, plague or taxes.

What we have seen this week is largely the product of a solipsistic media caste heavily influenced by their own personal priorities - the same phenomenon that produced the wall-to-wall coverage when Nelson Mandela died in 2013. It's all part of a growing trend towards collective sentimentality - remember 'the People's Princess'? - and an emphasis on the outward display of emotion, whether genuine or synthetic.

While I applaud the unseen hand that put Bowie on the PA system in my local shopping centre last week - infinitely better than the usual X-Factor warblings - and I may well play my CD of 'Ziggy Stardust' in the car this weekend (and sing along if there's no one listening), I see no reason to join in with a communal and irrational manifestation of grief played out to the extent that the mourning becomes in itself the news story.

There is a certain irony in the media descriptions of Bowie's quiet last months with his family and the private cremation interspersed with lurid accounts of candlelit vigils by tear-stained, elaborately-dressed fans (or, more correctly, fanatics). According to one paper, 'Rosie Lowery, 21, who painted her face with a lightning bolt in tribute, was crying as she laid flowers in Bowie's memory'; is it cynical to think that young Rosie's touching display may owe more to the omnipresent news cameras than to veneration of an ephemeral persona created twenty years before she was born?

Still, regardless of my views on conspicuous lamentation, I have to say that I have admired Bowie's musical and creative talent since I first heard 'Space Oddity' as a science fiction-obsessed teenager. Clearly I am not the only one for whom the song had a certain resonance - the internet sensation generated by Commander Chris Hadfield's performance suggests a sizeable intersection of enthusiasts (though it helped that Hadfield had already achieved online fame with his excellent tweet about having to wear a red shirt).

That being so, it is, perhaps inevitable that - and I've been saving this treat until last - there is an asteroid out there called David Bowie. It's not likely to be dropping by Earth any time soon but there's something rather agreeable about the idea of it sailing on eternally through the asteroid belt; perhaps, if online speculation proves correct, it will one day be joined out there in space by the cremated remains of the man himself.

Trick or Treat?

No, it's not the reappearance in the media of Camila Batmanghelidjh - don't worry; we'll have more on her soon - but a Hallowe'en Special in the form of 2015 TB145.

Data released this morning show that this asteroid, estimated at between 290m and 650m in diameter will fly by around 450,000km away - a mere whisker in cosmic terms - at an 'unusually high' relative velocity of 35km/s.

For those of us near the Greenwich meridian, the closest approach will be around teatime on Saturday October 31st - too early, perhaps, for the Tavern's traditional fly-by carousing but about the right time for a celebratory slice of cake.

At such proximity, there is always an outside chance that some unforeseen perturbation in its orbit may nudge it Earthwards - the Express is doubtless even now preparing its 'DOOMSDAY!' headlines - to send some of us, at least, the way of the dinosaurs.

If that is the case, what better day for the fire and flood to strike than the annual festival of tat and pointless consumerism that has swollen in recent years to a monstrous, bloated retail extravaganza?

What makes it even better is that, should the alarm genuinely be raised that day, the public response might well be the reverse of that inspired by Orson Welles' 'War of the Worlds' - secure in their assumption that it must be a seasonal hoax, countless thousands would, instead of retreating to higher ground, spend their final hours on Earth clad in scratchy polyester costumes eating themselves sick on chocolate eyeballs.

Sense at last!

Double cause for celebration today; not only will 2015 OQ21 soon be whizzing by a mere 568,000 km away but a journalist has, at long last, said the hitherto unsayable.

History, they say, is written by the victors. Mainstream media opinions on working mothers, in the same way, tend to be written by women who have delegated at least some of their childcare to other women (men, of course, would not dare to pronounce on such a contentious issue and childless women tend to keep their own counsel).

While full-time mothers hover around the edges in comment threads or the blogosphere, the floor of mainstream media and political coverage is firmly held by working mothers intent on justifying their own course of action.

It's also worth noting that we hear little from women who have returned after a full career break; the reason for that becomes lamentably clear when trying to get back into the workplace after a prolonged absence.

I've made my views on this issue known here before* but it is a breath of fresh air to read this from Sarah Vine (or, as she is also known, Mrs Michael Gove):
...the whole concept of childcare has a way of short-circuiting our internal feminist wiring. On the one hand, it’s our right to have meaningful careers; on the other, it’s also our right to have children. 
There’s just one tiny problem: who’s going to look after the kids? 
That is the great paradox of feminism: for every woman forging ahead in the workplace, there’s another taking her place in the home.
Regular readers may recognise more than a little similarity to a post which appeared here last November: 'There are plenty of high-flying self-styled feminists who apparently see nothing incongruous in their household outsourcing the domestic chores to an assortment of low-paid females.' 

Admittedly, it's taken her a while to see the light - she describes having been, in effect, a 'benign but distant' fifties-style 'father' to her young children for years - but better late than never; the response of her children has clearly convinced her that being there for them is the right thing to do and, to her credit, she has admitted it publicly.
Fact is, nannies make life possible for working mothers, but they are no substitute for being a parent. That, I’m afraid, is the one thing you simply cannot delegate.
Two glasses will therefore be raised in the Tavern this evening; 2015 OQ21 and Sarah Vine, your very good health indeed!


*Essentially this:'I firmly believe that a woman is the intellectual and social equal of a man and should be treated as such - with the proviso that a dependent infant is biologically more important than either man or woman and its needs should come first.'

Happy Asteroid Day!

Here at the Tavern we like to think that every day is Asteroid Day, but today it's official; the word 'bandwaggon' springs irresistibly to mind as the mass media weigh in with exclusives on every side, aiming to outdo each other with tales of near misses and earth-skimming behemoths.

As  it happens, we've had one of these in our sights for a while; July 7th brings us the whopping 65m+ 2015 HM10 a mere 442,000km away - rather less than ten times the length of the Pan--American Highway - which probably justifies some serious carousing.

The Metro, striking out at something of a tangent, has chosen to gratify readers of an apocaholic disposition by outlining an assortment of other interesting ways in which our species could be wiped out and concluding that an asteroid strike might not be such a bad way to go, considering. While sadly lacking in detail, it does, at least, provide a refreshing change to the general hysterical hyperbole over space-rocks passing safely by at nearly 20 lunar distances.

Asteroid Day, meanwhile, largely amounts to a massive public awareness campaign (for those who are not regular readers of this blog) and an invitation to sign a declaration calling for:
  • Employ available technology to detect and track Near-Earth Asteroids that threaten human populations via governments and private and philanthropic organisations.
  • A rapid hundred-fold acceleration of the discovery and tracking of Near-Earth Asteroids to 100,000 per year within the next ten years.
  • Global adoption of Asteroid Day, heightening awareness of the asteroid hazard and our efforts to prevent impacts, on June 30, 2015.
While deploring their slightly iffy grammar and wondering what happens to resolution 2 if there are insufficient asteroids out there to meet the target of 100,000 discoveries a year, I can say that the third of these is an aim I support wholeheartedly - not least because it's an excellent excuse for a party.

Meanwhile, matters astronomical are to the fore today in the form of the leap second to be added tonight to keep atomic clocks in line with the earth's rotation. My favourite coverage of the story is this 'down wid da kidz' version from Radio 1's 'Newsbeat' page:
[Last time it happened]  In 2012 a number of big websites including Mozilla, Reddit, Gawker, LinkedIn, FourSquare and Yelp were caught out and went a bit wrong.
Newsbeat got in touch with Robert Edwards, head of science at the Royal Observatory Greenwich - the place were [sic] time in the UK is kept. 
As a bonus, they helpfully include a picture of  'a clock at Newsbeat HQ' so their readers can be sure what they are talking about.

And, as if that were not enough, Jupiter and Venus are joining forces, at least from our perspective, this evening to put on what out distant ancestors would have seen as a spectacular lightshow - though it's likely to be less of a novelty to our jaded 21st-century visual palates.

All in all, then, I think this calls for a celebration; I invite you to join me in the Tavern (though  you may need to dust off the bar-stools) and raise a glass to Asteroid Day - many happy returns!

Incoming!

Another opportunity this week to indulge in a favourite pastime; it seems someone forgot to put on the handbrake of a Russian spacecraft and, as it begins its slow but inexorable descent - currently predicted (for the UK, at least) to end in the early hours of 9th May (+ 48 hours) - those inclined can enjoy speculating where it would do the most good, should it arrive down here as an assortment of red-hot fragments.

In general, I try to be well-disposed towards my fellow man, but I have to admit there are several people I should be very happy to see on the receiving end. Actually, I like to envisage an asteroid strike which, unaccountably, finds them all gathered together in the impact zone, but I'd settle for some Russian space junk in the meantime.

Once the MSM get hold of it, this will doubtless lead to a repeat of the speculation which, during the 6.5-tonne UARS satellite's decaying orbit, led to entertaining headlines like 'Britain in path of falling satellite' - an assertion owing rather more to dramatic effect than to accuracy.

Though there has been little time for posting recently, we have been diligently drinking to the near-Earth asteroids of the past few weeks - including the house-sized 2015 HD10 passing by at 627,000km today - and keeping an eye on the treasure hunt that has resulted from Sunday night's Irish fireball.

Over the next few days though, we'll mostly be following the runaway space freighter's orbital path and current altitude at Satflare, where the tracking display proves strangely hypnotic.

Six of the best

It was the usual Ankh-Morpork mob in times of crisis; half of them were here to complain, a quarter of them were here to watch the other half, and the remainder were here to rob, importune or sell hot-dogs to the rest. (Terry Pratchett, 'Guards! Guards!')
It's been quite a week for asteroids. According to a fellow enthusiast:
...on March 10, 2015, a 12–28 meter asteroid dubbed 2015 ET cosmically “just missed us”, zipping past Earth at 0.3 lunar distances – 115,200 kilometers, or 71, 580 miles.
Then the pocket-sized 2015 EO6 - possibly the subject of this video - whizzed by a similar distance away, followed by 2015EQ and 2015 EK (both between 15 and 33m in diameter) and the slightly smaller 2015 EF and, today, 2015 EO all passing a mere million or so kilometres above our heads.

The startling number of close fly-bys detected recently, even if they aren't of a size to send us the way of the dinosaurs, makes it much easier to appreciate that an asteroid strike isn't a matter of 'if', but of 'when'.

Eschatology aside, I rather suspect most of us aren't exactly prepared for this. True, official bodies have been undertaking mock exercises, which has to be a good thing, but, on an individual level, I don't see much hope for a sensible and reasoned reaction.

Part of the problem is the constant cries of 'Wolf!' from the media. We've become accustomed to a sort of semi-permanent wibble about everything from global warming to imminent food shortages in the Home Counties while life goes on seemingly unaffected; like children dropping crisp packets on their way home from yet another anti-littering PSHE lesson, the population has ceased to take any notice of what is being said.

Occasionally, however, a particularly alarmist message gets through and we are treated to the edifying sight of supermarkets besieged by shoving hordes squabbling over the last baked goods, fearful lest a threatened snowstorm should delay deliveries and plunge them into an appalling carbohydrate shortage. So used are we to instant gratification that even the mildest of deprivation seems to bring out the worst in some people.

Should a diminutive asteroid land on some part of our green and pleasant land tomorrow, I hope the affected population will find some measure of altruism and organised response. Failing that, I fervently hope those most likely to act selfishly or exploit the situation are squarely underneath when it hits (along with a few particularly deserving cases; I have a carefully-maintained mental list).

Meanwhile, every fly-by is an excuse for a drink and this week, in spirit at least, we will be broaching a bottle of Jimkin Bearhugger's finest to drink to all six, before raising a seventh glass in salute to the much-lamented Terry Pratchett.

I think this counts as a full house; you wait weeks for an asteroid inside the 5,000,000km mark and then five come along at once.

What makes it even more interesting is that four out of the five were detected within the last two days, along with the departing 2015 CH13, a 10m-wide cosmic tiddler which passed a mere 268,000-odd km away on Wednesday.

And, to top it all, today being the second anniversary of the Chelyabinsk airburst, the B612 Foundation (the organisation behind the Sentinel mission) has decided it is an appropriate time to remind us of the dangers of asteroid impact.

It's a warning we've heard before but, this time, the focus is on the small fry - rather like today's visitors, in fact - with former astronaut Dr Ed Lu reassuring us that, for a small asteroid, deflection should be relatively straightforward:
"In most cases, simply running into the offending asteroid with a small spacecraft is sufficient."
Unmanned, one hopes. There's surely a film script in there somewhere but, to be honest, it's not exactly up there with Bruce Willis and the nukes, is it? Perhaps Hollywood will instead turn its attention to the drama of mass evacuation, now that planned detection systems may give enough warning to clear the impact areas in time.

With a matter of hours of warning - if any at all - this week we are certainly not yet at that point; in fact, a cynic might be tempted to wonder whether, had one of the five been heading straight for us, the authorities would have passed on the news at all. The potential for civil unrest and administrative chaos might well make public ignorance the preferred option.

On a more positive note, since every fly-by (or safe departure, depending on your attitude) deserves to be celebrated with a brimming tankard, tonight looks like being a good one - I invite you to join me in a toast to five near misses.

Cheers!

Fly-by night

After a quiet few weeks, the Tavern doors are open again to celebrate the 27-metre wide 2014 WC201, which passed a mere 540,000km above our heads this morning too early, in the UK at least, for anything but a bleary wave.

For those sorry to have missed it - though you could always have a drink to speed it on its way - there may be consolation on the way in the shape of the 2014 WX202, a mere 5m tiddler in cosmic terms but due to pass 380,000km away on the 7th at the decidedly more congenial time of 7.56pm.

I say 'may' because, rather embarrassingly, its low relative velocity and trajectory suggest that this latter visitor may not be quite as extra-terrestrial in origin as originally thought.

Along with the space-rocks, there's a fair bit of our own litter out there and it's quite possible that 2014 WX202 is actually a bit of orbiting scrap like the one temporarily mistaken for an asteroid last year in the spacegoing equivalent of an angler landing an old boot.

If Professor Hawking's predictions about artificial intelligence are accurate, our future robot masters are likely to find us more than a little risible (always assuming they have developed something that passes for a sense of humour); we shove a load of metal into an interesting variety of orbits, then get all excited thinking it's an asteroid when it sails past - at least until we discover it's coated in titanium paint.

And should ET and his chums be out there, it's a fair bet they will take one look at the assorted scrap metal that litters our immediate environment and decided that we really aren't the sort of beings they want to get acquainted with, at least until we've done some housework.


Update: The Astronomer Royal, former astronaut Ed Lu and Queen guitarist Brian May have just unveiled plans for a global Asteroid Awareness Day on 30th June 2015. While we like to think that, here in the Tavern, every day is Asteroid Awareness Day, we certainly aren't going to pass up the excuse for a massive party!

Of mud and stars

Oh dear; decisions, decisions!

Returning from a few days of bracing (if somewhat muddy) walks in one of the more picturesque parts of the country, I am faced with not one but two irresistible topics.

Firstly there is 2014 UF56, a bus-sized asteroid passing by a mere 158,000 km above our heads just after 9pm tonight - have your glasses filled and ready!

And secondly, to brighten up a dark October evening, there is the boy racer who spent yesterday watching his pride and joy sink slowly into the mud near Burnham on Sea.

We have, of course, reported from the area before;  despite warning signs and publicity, a combination of Britain's biggest tidal range and vehicle access to the beach is clearly too much temptation for some.

Just a few months after a father-and-daughter team discovered the hard way that coastal mud makes a less than ideal driving surface, a 22-year-old from Bristol decided that his Saturday night would not be complete until he had taken his souped-up Celica for a spin on the beach.

Finding himself inextricably embedded in mud over the axles with an incoming tide, he abandoned the vehicle (and his chances of a Darwin Award - this time, at least) and escaped to shore. Recovering the car, however, has proved considerably more problematical, as the pictures show.

And there's more to enjoy in the comments:
It's got a GT-Four boot spoiler on it but DVLA states that it's a 1762cc car, which means it's not actually a GT-Four (they were 2 litre).
So, a Saturday night boy racer and a poser; our cup of Schadenfreude runneth over!

Speaking of which, it's about time for our annual musical comment on Sober October; after a sparse few months, we are entering a reasonable crowded part of the orbit - last Friday produced the undeniable convenient 2014 SC324 - and can look forward to plenty more close approaches in the near future.

The man who drinks cold water pure
And goes to bed quite sober
Falls as the early leaves do fall
So early in October,
But he who drinks just what he likes
Until he's half seas over
Shall live until, until he dies
And then lie down in clover.

A bad case of asteroids

A busy week, but I couldn't let a passing space rock go untoasted even though it seems to have attracted a media frenzy - many happy returns, 2014 RC!

In the best churnalistic tradition, if one science editor picks it up then all the rest follow - never mind that other very close approaches go unmarked save by astronomical websites and the occasional obsessional blogger.

Once again, I feel rather peeved; it's like being a die-hard fan of an obscure indie band which has inexplicably gone mainstream and appeared on Saturday night television, complete with gyrating dancers and laser displays.

Perhaps this is something to do with the opportune appearance of the media-savvy Professor Brian Cox as (appropriately enough) honorary Chicken Licken to the nation, a position left vacant thanks to Lembit Opik's apparent desertion of the cause for rather more earthly attractions.

The media coverage inspired the Express, in particular, to hyperbolic flights of fanciful prognostication:
ASTEROIDS could rain down on the earth for 100 years, shocked experts have just warned.
which in turn, prompted this excellent debunking at Slate Magazine.

Meanwhile, investigators have been called in to assess a new crater in Nicaragua, which has raised the interesting question of fragmentation, bane of the Bruce-Willis-and-the-Nukes school of asteroid impact prevention.

According to JPL and NASA:
For those wondering, the event in Nicaragua (poss meteorite?) is unrelated to asteroid 2014 RC. Different timing, different directions.
which brings to mind the recent coincidence (?) of the Chelyabinsk meteor and DA14; will we one day be blindsided while all our attention is centred on another rock passing overhead?

All in all, it's a salutary reminder of our own insignificance in the face of whatever is hurtling round out there. In the words of John W Campbell (as quoted by Arthur C Clarke):
'Meteorites don't fall on the Earth. They fall on the Sun, and the Earth gets in the way.'

Profit of doom

If you're planning to jet off for a late-August holiday abroad, it might be an idea to work out an overland route home just in case.
Iceland's Met Office on Monday raised its risk level to the aviation industry for an eruption at its Bardarbunga volcano to orange, which is the fourth level on a five-grade scale.
The alert has been prompted by an 'earthquake swarm' in the area. While there's no sign of an imminent eruption, the local authorities are concerned enough to have closed roads in the area as a precaution against floods caused by melting of the Vatnajokull glacier.

An explosive eruption could produce an ash cloud similar to the one that grounded European aircraft in 2010 (regular readers may remember the saga of the nephew stranded in Sicily after a field trip to study a resolutely uncooperative Mount Etna - should have gone to Iceland!).

It was a massive eruption in the Vatnajokull area that led to catastrophic famine in Iceland in the 1780s and arguably contributed to the French revolution by causing crop failures in France; while the Icelanders are now far better equipped to survive, the impact of a similar event on the aviation industry today would have far-reaching economic consequences.

It's a salutary reminder that Nature has plenty of surprises up her sleeve for those who rely too heavily on modern technology. Still, at least it appears that the recent rumours circulating of an imminent Yellowstone supervolcano eruption - also based on seismic activity - have been dismissed as a hoax.

We predicted a few months ago that, with the summer dearth of asteroid close approaches and nothing scoring more than 0 on the Torino Scale, apocaholics would be looking elsewhere for thrills 'so look out in the coming months for dire predictions of mega-tsunami, solar flares and the release of methane clathrates'.

Sure enough, in recent weeks we have been treated to
Killer solar superstorm could destroy Earth at ANY MOMENT, scientists warn (Express)
along with the interestingly forthright
'We're f*****': Climate change will be catastrophic for mankind after study reveals methane leaking from the Arctic Ocean, scientist warns (Daily Mail)
and, although no mega-tsunami scares have emerged recently, the media have been making up for it with exciting headlines about the 'killer asteroid headed straight for us' which actually translates as 1950 DA's 1-in-300 chance of impact eight centuries hence.

The prospect of a potential volcanic eruption in the near future must therefore have been greeted with delight in many newsrooms, however grimly it may be viewed by those potentially on the receiving end. In short, disaster sells.

Meanwhile, in the Tavern, it's been a long time since we toasted a passing space rock and the next one isn't due until mid-September.

Perhaps we should start drinking to volcanoes as well.


Update: The Cynical Tendency takes a more intellectual approach and examines the political implications of a serious eruption.

Flying tonight

Another asteroid, another drink!

When we began the practice of raising a glass to every near-Earth asteroid five years ago, we didn't realise quite what we were letting ourselves in for. This chart gives some idea of what we're up against, even given the fact we don't usually pop the cork for anything over 1.5 million km away.

(There's lots more discovery data at the source: NASA/JPL)

According to Universe Today,
As of May 30, 2014, 11,107 near-Earth objects have been discovered with 860 having a diameter of 1 km or larger. 1,481 of them have been further classified as potentially hazardous.
To earn the designation of 'potentially hazardous', they need to approach within 7.48 million km and be at least 150m across; the sort of thing that would make a very nasty mess indeed should one ever turn up here. While every asteroid catalogued is one less unknown, there's something unsettling in the idea that we have only had a few days notice for most of the recent near misses.

While optimists talk of untold riches mining asteroids and plans are afoot to capture one and park it somewhere convenient, we should not forget the words of NASA's chief when asked what we could do if an asteroid were discovered to be heading straight for us: "If it's coming in three weeks, pray."

Anyway, if you're at a loose end with a glass in hand at 9pm (BST) tonight, the virtual telescope will be covering the flyby of the newly discovered 22-metre-wide 2014 KH39, which will be whizzing past 432,000 km above our heads at a decidedly nippy 25,000mph.

Bottoms up!

Back again!

So... I've opened the shutters and removed the worst of the dust in Tavern following a short absence; did anything important happen while I was away?

Certainly the election seems to have produced a predictable crop of nannying politicians telling us that the voters who failed to succumb to their blandishments and voted UKIP didn't really mean it  - "It's not big and it's not clever" - and Man's myriad inhumanities to Man (and Woman) continue, alas, unabated.

One thing that turns out not to be happening is the future impact of a 10-mile-wide asteroid, a headline which caused a media sensation on CNN's citizen journalism website:
"The asteroid is calculated to have a potentially lethal encounter with the Earth on March 35, 2041 [sic]"
Now, of course, the news story is 'Earth NOT to be hit by killer asteroid', which takes reporting of non-events to a whole new level. The whole thing appears to be the result of an enterprising hoax combined with lax editing at weekends.

Those of an apocaholic disposition who find themselves unaccountably bereft as a result can take small comfort in the fact that today brings a bumper crop of near-Earth approaches - six known ones in all - ranging from the 'big and far away' 2014 GD45, several hundred metres wide, to the diminutive 2014 KC45 passing a mere 80-odd thousand miles above our heads.

Five of these are recent discoveries, courtesy of new, improved surveillance. The recent spate of newly identified space rocks has been so dramatic that it has - mirabile dictu! - even brought about the return of Lembit Opik to the asteroid fold (and thence to a call for Clegg to resign; the leopard definitely hasn't changed his spots).

This is cheering news; although it appears Opik has been keeping the flame alight on the speaker circuit, he has, of late, been more active in other spheres when celestial bodies have hit the news. Perhaps his ill-fated foray into dog-show judging has finally convinced him where his true métier lies.

Despite the increase in the numbers, we still aim to drink to every near miss, which makes this evening something of a gala occasion; you are very welcome to pour yourself a drink (or six) and join me in a toast to tonight's clutch of space rocks.

Cheers!

Heads-up!

Asteroid update - the diminutive 2014 JR24 will be flying by this morning round about time for elevenses in the UK.

Though only a few metres wide - on Asteroid Watch's pictorial scale (truck, bus, jumbo jet etc) it is rather sweetly represented by a small hatchback- it will be skimming by a mere 100,000km above our heads.

While an impact from something this small would be unlikely, in planetary terms, to cause more than a little local difficulty (albeit providing a highly unpleasant experience for anyone standing underneath), it's a reminder of the constant presence of these space rocks - and an impressive display of the level of detection now possible.

As the animation released by the B612 Foundation last month demonstrates, there are plenty of the things around; 26 impacts to Earth or our atmosphere between 2001 and 2013 show just how lucky we have been so far.

JR24 is, sadly, passing rather too early in the day to be greeted with a serious drink but, in our usual spirit of marking the occasion, we at the tavern will be lifting a coffee mug in salute as it travels on its way.

A date for asteroid-spotters

Since every fly-by is an excuse to raise a brimming tankard or two here in the Tavern, we have been merrily celebrating the passage of 25-metre-wide 2014 HL129 a mere 300,000km away on Saturday.

What's more, today brings us the newly-discovered HX164 (~12m, 430,000km away) and HB177 (~7.5m, 500,000km), both very small fry and sadly too late for a bacchanalian end to the weekend but no less significant for that.

The new detection systems have dramatically increased the number of known Near Earth Objects (and the Tavern drinks bill) and given much ammunition, so to speak, to the organisations devoting their energies to developing strategies to deal with the risk of potential impacts.

Following last month's conference sponsored by the B612 Foundation, this week sees the first 'Stardust Global Virtual Workshop (SGVW-1) on Asteroids and Space Debris', based rather closer to home in Glasgow.

This is happening under the aegis of Dr Massimiliano Vasile - remember him? Brain the size of a planet but not the snappiest of orators? - whose international research project is holding an 'open forum to collect the latest advancements in asteroid and space debris science and technology'.

The first of the event's two public lectures - 'Avoiding the Fate of the Dinosaurs' - can be seen tonight at 7pm on Youtube (follow the link) and the second - 'Looking Towards the Galactic Frontier' - at the same time on Thursday.

They're behind you!

Having said yesterday that there was little happening on the asteroid front, I am delighted to have been proved wrong.

Eagle-eyed astronomers have just published close approach data for two bus-sized asteroids which passed us undetected last Wednesday and Thursday, both around the 700,000km mark, and were observed two days later.

While these were relative tiddlers and probably not easy to spot, the fact remains that they were not seen until they were on their way back into the void. This is somewhat disquieting, taken in conjunction with the recent announcement from the B612 Foundation (charmingly named after the asteroid home of Saint-Exupery's 'Le Petit Prince').

At a conference later this month, CEO and former astronaut Dr Ed Lu (as regulars may remember, we've met him here before) will unveil a video representation of data from the Nuclear Weapons Testing Network:
This network has detected 26 multi-kiloton explosions since 2001, all of which are due to asteroid impacts.
Dr Lu's expert opinion is worryingly clear:
The fact that none of these asteroid impacts shown in the video was detected in advance, is proof that the only thing preventing a catastrophe from a “city-killer” sized asteroid is blind luck.
I'll drink to that!

(I'll also be drinking to another flyby tonight's - 2014 GN1, 40m wide passing at around 937,000km - so please feel free to join me and raise a virtual glass in salute.)

The end of the world is a little less nigh

There's sad news this week for those of an apocaholic disposition.

Recent observations have downgraded the impact threat from 2007 VK184 from its previous score of 1 on the Torino scale, meaning that, since the same thing happened to 2013 TV135 last November, there is now no asteroid scoring higher than 0.

To put this into perspective, the Torino scale of potential asteroid impacts, after 0 (no threat), goes from 1: 'A routine discovery in which a pass near the Earth is predicted that poses no unusual level of danger' to 10: "Oh shit! It's heading right for us!"

(Or, as the scale rather more sedately puts it, 'A collision is certain, capable of causing global climatic catastrophe that may threaten the future of civilization as we know it.')

Of course, there are still the known unknowns out there, giving us the very real possibility that oblivion may strike without warning, but we are no longer, as NASA's finest would say, 'in  a non-zero impact probability situation'.

That being so, apocaholics must look elsewhere for their thrills, so it is fortunate that, right on cue, footage of herds of bison (or, if you prefer, buffalo*) 'fleeing' from Yellowstone has gone viral - "Hey, fellas, the big one is about to go pop!"

Fuelled by the announcement of the Park's biggest 'quake for more than three decades, US survivalists have gone into overdrive preparing for the eruption of the Yellowstone Supervolcano and the potential resulting ash cloud, helpfully encouraged by lurid online speculation.

The explanation, according to experts, is far less exciting. Earthquakes are hardly unusual in Yellowstone and the beasts were simply following their usual winter grazing migration pattern; on the day the 'stampede' was filmed, they were unusually frisky because of the spring sunshine.

With the absence of any known asteroid threat and a quiet few months in prospect - there are only a handful of approaches closer than 1.5million km predicted for the rest of this year - apocaholics clearly have to get their kicks where they can, so look out in the coming months for dire predictions of mega-tsunami, solar flares and the release of methane clathrates.

There is, after all, no such thing as a redundant prophet of doom.


*By coincidence, the same buffalo (or bison) are currently in the news because of the proposal that the Nez Perce tribe should be allowed to hunt them inside the National Park - concerning, as it does, competing claims of animal rights, Native American culture and environmental protection, the subject has produced a veritable cornucopia of intellectual contortions from readers of the Guardian.

Crowded Skies

It's been a busy week but there's still time to raise a glass to the two asteroids that passed by this morning a whisker over a million kilometres away.

Though relative tiddlers on a cosmic scale - 13m and 26m respectively - 2014 EP12 and EB25 surely merit a toast, as does 2014 EX24, which literally slipped under the radar last Sunday and wasn't spotted until two days after its closest approach at around 260,000km.

As an ideal accompaniment to your drink, assuming you are in a reasonably robust frame of mind, you might like to contemplate the work of some some enterprising astronomers who have created, in effect, a prototype Total Perspective Vortex.


(For those unfamiliar with the works of Douglas Adams: The prospective victim of the TPV is placed within a small chamber wherein is displayed a model of the entire universe - together with a microscopic dot bearing the legend "you are here". The sense of perspective thereby conveyed destroys the victim's mind.)

Scotch for the rocks

A positive cornucopia of asteroids at the moment: yesterday brought us the 25-metre 2014 DX110 at a distance of 348,000 km and today a double helping in the shape of 'very small' asteroids 2014 EF at 120,000km and 2014 EC at 62,000 km.

Since we are in the habit of celebrating every flyby with a drink or two and things are very busy in the Tavern, I have decided to devote the rest of the evening to getting comfortably horizontal.

If you dropped in in search of entertainment, I do apologise; please feel free to have a wander through the archives or, if you prefer, pour yourself a drink and join us in a virtual toast to 2014's latest crop of asteroids.

Lost, stolen or strayed

There was cheering news recently for those of us of an absent-minded nature; something went missing this week besides which all those car keys, glasses and phones pale into insignificance.
The 270-metre space rock known as 2000 EM26 was slated to skim past Earth early on 18 February, coming within 3.4 million kilometres of our planet.
So far so routine - it's been a busy week and we don't tend to get excited unless an asteroid gets closer than 500,000km or so - but there's more:
When a robotic telescope service trained its eye on the predicted position, the asteroid was nowhere to be found.
Oops! Admittedly there's very little chance of it heading in our direction, though it's a happy coincidence that the Viking Twilight of the Gods is, in theory, due this weekend. (Other predicted events of Ragnarok include earthquakes and vast floods, just to let you know...)

The first thing you usually ask when something goes missing is, "Now, when did I see it last?" In the case of 2000 EM26, it was back in 2000, when it was discovered and briefly observed by astronomers. As a result of those calculations, observers at SLOOH lined up their lenses ready for a live broadcast of the flyby this week.

Instead, like hopeful paparazzi outside a stage door, they waited... and waited... and waited. Although there is usually some measure of uncertainty, it's not entirely reassuring, given the number of the things hurtling round out there, that there is such a substantial margin of error.

Now SLOOH's CEO has been reduced to putting up forlorn notices on the virtual lamp-posts of the internet calling on amateur astronomers to keep an eye out for the thing. Sadly there's no reward - just honorable mention on their website.

Still, if you happen to see a large space rock hurtling past you this weekend, it might be kind to let the chaps at SLOOH know about it - unless, of course, it's headed straight for us, in which case apocaholics of a Viking persuasion are in for the ultimate treat.

See you in Valhalla!
