I understand that when we look at a DSO (or any object), that we are
looking at the DSO the way it looked at some time(t) in the past. In
this respect, we are looking at a snap shot of the past.

But what exactly are the astronomers expecting to see? New galaxies
not seen before due to their extreme red shift?

Would you like to be the first to answer this question correctly.

You know that our solar system is moving with the rest of the local
stars around the Milky Way axis.

If you look at an external galaxy,say the Whirlpool galaxy,what would
you expect to happen after 1 million years ?.Remember the foreground
stars of the Milky Way are orbiting the galactic axis therefore we are
moving like a system on a giant carousel.

The idea is to develop the feel for cyclical motions and how to use the
illusion created by radiation having a finite speed just like Ole
Roemer used the orbital cycles of the Earth and Jupiter to determine
that light generates an illusion as we look into the celestial arena
where all the great cycles exist.
