Primordial Helium

smk writes: "NASA's Far Ultraviolet Spectroscopic Explorer (FUSE) satellite has given astronomers their best glimpse yet at the ghostly cobweb of helium gas left over from the big bang, which underlies the universe's structure. The helium is not found in galaxies or stars but spread thinly through the vastness of space. The helium traces the architecture of the universe back to very early times."

I want to know about Artist's Concepts.

[taliver]

Completely off topic, but exactly where do they find these artists with concepts? Every scientific paper dealing with subatomic physics or astronomy has some "artist's concept" picture in it.

Now, I know several artists, and I wouldn't trust them with anything even remotely scientific. So, is there a "scientific art" major in college that I don't know about? Or does NASA and the like have some artist on payroll who attends all the meetings and then just draws what he's thinking about?
