It is collosal, and about 4Bly away. It almost appears as a nebula with stars.

OMG those are all galaxies, not stars! So it's gotta be galactic. Must be some glowing gases, but on a galactic scale. I'm close, judging from the previous replies!

The question is "Where in the Universe?"
Answer: about 3.8 billion light years away.

Merging galaxy cluster 1E 0657-55.8 (aka 'Bullet Cluster') imaged by Chandra in x-rays and a color composite by the Magellan telescope in Chile. Awesome composite image!

Bullet cluster it is!

Some date? Maybe if it is that female gaseous being I mentioned, otherwise I meant "data".

Oh, and I believe that this image may contain some date from the Magellan telescope in Chile.

It is either the Bullet Cluster, spacecraft Chandra and Hubble OR an intelligent female gaseous being that fell in love with a human male in Star Trek; the original series. It wasn't Captain Kirk that it fell in love with either!

Bullet Cluster with Chandra… but Nereid beat me to it

It looks similar to Abel 901, but there are departures in the images. The bow shock makes me suspect this is a more local nebula.

One of the X-ray observatories – Chandra or Newton – I don't remember.

Judging from the bow shock, I think it's the original Bullet Cluster – the first collision of galaxy clusters to show Dark Matter. Not in this image – the red is the gas heated in the collision.

The Bullet Cluster; the pink is x-ray emission (per Chandra), the rest is optical (per Hubble, but I don't know the camera – ACS?)

This is a galaxy cluster, I think, within a cloud of molecular hidrogen. But I can't say which one. The image is a composite of a visible picture with another taken in different wavelengths (far infrared? Probably) Hubble and Spitzer perhaps.

Or maybe I'm utterly wrong…
