This is the Picture of Temperatures/Densities in the Cosmic Microwave Background. It was taken by the WMAP satellite!

background will backlight everything that we can see. Most things don’t really interact with these cold photons… but some things can. The hot gasses surrounding giant clusters of galaxies.

and so, we can see the shadows of these things in the cosmic microwave background pattern!

OH MAN OH MAN!
