Question

How many galaxies are astronomers studying?

Answer 1

We are really not sure.

Explanation:

Depends on what you mean by studying.

Since there are a lot of telescopes both in space and on the ground that can observe galaxies billions of lightyears away, and with instruments such as the spectrometer. If studying it is simply take a few pictures of it and try to find the number of stars it has, we've probably done this millions of times already.

But study ing, we are not sure because the people doing the research on the galaxies won't release their data, and people won't count them even if we do have them.
