When we look at a picture of a galaxy, how is it possible that we see a disk form or a near perfect circle? Considering how long light takes to travel between the galaxy and the earth, shouldn't the images be more distorted?

The answer is quite simple. Telescopes in outer space, such as Hubble, take pictures of those galaxies not the ground based telescopes.

Explanation:

This is because our atmosphere distorts the light coming from the cosmos. Telescopes in space can take much more clearer pictures and that's how the perfect circle of galaxies are visible to us.
