Lowest natural temperature
You can do a few picoK in the lab
If you're searching for the ideal place to hold your Halloween party next Thursday, may we suggest the Pac-Man-ghost-shaped Boomerang Nebula in the constellation Centarus? The Boomerang Nebula in the constellation Centaurus, as imaged by the Atacama Large Millimeter/submillimeter Array (ALMA) telescope 'Casper, the Friendly …

I thought the coldest thing in the universe was a witch's [something one exchanges for tat].
But the thing that really puzzles me is how the IBS treatment Molecure relates to nebulae.
"[something one exchanges for tat]"
I actually thought you were going to say that it _rhymes_ with tat :)
Is a witch's cat really that cold?
Must be all that flying about at night, perched at the rear of the broomstick....
Colder than a witch's tit? Not colder than a well-digger's arse? Never having measured either, I wouldn't have the foggiest.
You obviously haven't met my ex then (you lucky, lucky bastard - apologies to Monty P and LoB).
That witches heart would make this nebula feel like a sauna in comparison.
"Coldest Place In The Universe"
Hmmm not sure about that.
At 1 degree Kelvin it is rather warmer than the 1 nanoKelvin reached at MIT
So I would say that as it is one billion times warmer it is not quite the coldest place in the universe.
Is that place where that temperature was achieved still that cold?
Or did they turn the machine off?
I am pretty sure that it's currently no longer as cold as it was, there maybe some other experiment running currently which is making a specific location cold for a short while, but let's face it, they're really not going to stay colder than this place in any kind of timescale that's going to appear on a geological clock.
The 1 nanoKelvin reached at MIT is rather warmer than the 100 picokelvins reached by the boffins in Finland.
"The 1 nanoKelvin reached at MIT is rather warmer than the 100 picokelvins reached by the boffins in Finland."
I always thought 1 nanokelvin was the ambient temperature in Finland - listen to "The Swan of Tuonela"
Is this anywhere near the Pacman nebula?
Sounds like a good place to store my freezer food....
No it bloody well isn't. >:[
No wonder the Haudagain roundabout snarls up.
I'm pretty sure there will be some OAP's houses in Blighty colder than that this winter
Isn't that the evidence that our somewhat less than levelled headed chums in the Hubbardian Cult are looking for that Xenu exists as a ghostly hooded figure?
Nice article (and no sarcasm intended). Informative with a splash of Reg humour.
Fridges do *not* use "expanding gas" to cool themselves. They use the change of state of the refrigerant to cool themselves.
0/10. See me.
Wait, "literally the coolest thing in the universe"?
At 5000 light years away, I assume that it's inside our own galaxy.
Given that there are billions of other galaxies, how do we know that there aren't colder nebulae out there?
Seems that someone got careless with the word "literally".
"it's the coldest place in our known universe – colder even than a mid-winter night in Aberdeen"
Geordius Nocturnulus will still be out drinking wearing shorts and a t-shirt. It's never too cold for him!
Coat. 'Cos I'm one of those rare "soft" Geordies.
Hmm, lots of (well, several anyway) folks commenting on the careless use of "coldest in the universe". Yet the article states "it's the coldest place in our known universe", and the abstract of the paper it's based on states "coldest known object in the universe".
So either there's a bunch of commentards who really need to double-check their reading and comprehension skills, or both the article AND the abstract of the paper were corrected between the time the comments were posted and I read the article (about 15 minutes before this comment was posted - see posting date...).
It looks like a Space Invader to me, looks like there is only one left, I think we should fire phasers, and get ready for the mothership ...
Mine with too many quarters on one side. ------------------------>>
It's glowing because it's ionized gas illuminated by the radiation from the dead star, right?
It does seem remarkable that something both inside our galaxy and lit up could be that cold. That'll be a good use of a grant to work out a theory.
...have shed more light – or, actually, received more light...
Actually both. ALMA has received light from the Boomerang Nebula, and light has also been reflected by ALMA* towards the nebula (though that light won't reach the nebula for another 5000 years).
*and also by the top of my head
