55,000 light years across; 12.9 billion light years away.

Any ideas?

:confused:

ooh - Ta,
i was looking for that,
couldn't remember where the hell i'd left it. :rolleyes:

lose me own head next. :blast
 
It's where I'd like to be before my boss finds out what I've just done :blast
 
It might not look like much, but this image represents one of the most distant objects astronomers have ever seen, 12.9 billion light years away.

It is a "Lyman-alpha blob" and is 55,000 light years across - as large as present-day galaxies.

Though younger such blobs have been found, "Himiko" confounds the idea that such large objects grew more recently by the merger of smaller ones.

The research will be published in the Astrophysical Journal.

Current cosmology models hold that between 200 million and one billion years after the Big Bang, the first colossal stars formed, emitting radiation that stripped light elements of their electrons and turned the Universe into a soup of charged particles.

Only after this "re-ionisation epoch" did matter as we now know it really start to clump together.

Bloody obvious really. I'm surprised more of you didn't know :rolleyes:

Okay smarty pantaloons: Why is it posted in the 1200 section?

(Cue Greg with punchline?)

:mmmm
 
Its a heat seeking camera image of a Germans' brain that invented the GS
 
However, as Geach points out, "Many early theories of galaxy formation predicted a Lyman-alpha 'fuzz' around early galaxies", and went on to add "until we know more about their physics, their connection to the formation of galaxies, and perhaps most importantly their lifetimes, we don't really know how they fit in".

So it may as well be fluorescent hemerrhoid up a bears ar*e for all anyone really knows.

I must admit, however, it's a far more interesting question than many that I've seen on the site, especially those related to cleaning, oil and flat batteries.

Well done.:beerjug:
