are pictures of the universe theory in what a computer can generate from data it retreaves?

Generally they are exposed for a long time (sometimes hours) to allow light and detail to build up. Also some
astrophotographers take many digital pictures and "stack" them,
which increases detail.

Most of the pictures you see are taken with optical telescopes that gather a lot of light for a long time. Sometimes the colours are enhanced, sometimes they're completely artificial in order to bring out some interesting feature. Images can also be produced by processing data from radio telescopes. Because they can be made a lot bigger than optical 'scopes, there's often more detail in them.
The pictures from the HST get a lot of publicity, but have a look at David Malin's pictures taken with the Anglo Australian Telescope.

The Hubble Space Telescope!
It is so strong that, it can see 2 fireflies in Japan from the USA, or can see a penny on the ground from the empire state building

Well with the Hubble Telescope scientists were able to take clearer pictures aided by computer generation.

Pictures are taken with the Hubble. I have sent you a link so you can look at the site.

Resolution is the name of the game coupled with computer enhancement and pigmentation. basically the more light you can trap the better the picture.
