Of the naked eye galaxies - i.e. those visible with the naked eye. There are seven.
* Milky Way - Ours * Andromeda * Large Magellanic Cloud - Southern Hemisphere
* Small Magellanic Cloud - Southern Hemisphere * Omega Centauri - Cannibalised by the Milky Way * Triangulum Galaxy - Very Faint
* Bode's Galaxy - Very Faint

It is a large galaxy, which is relatively near-by. There are galaxies nearer to us, like the two Magellan Clouds; but those are mini-galaxies.
Most galaxies have a red shift away from us - meaning they are moving away from us. However, the Andromeda galaxy has a blue shift, which means it is moving towards us. In about 2.5 billion years time, the two galaxies will merge.
Most galaxies are moving away from us. Only a few galaxies, which are nearby, are moving towards us.
Mainly that galaxies that are very far away (i.e., from the distant past) look different to galaxies that are near-by (from the more recent past).
It tells us that most galaxies are moving away from us.
The closest ones near our galaxy.

That the galaxy is moving away from us.
Earth is the only planet we know of that has living creatures inhabited on it, Although even with our greatest technology today we cannot see other galaxies. There are millions of stars in our galaxy that could have planets near by. With a heat source it would be possible for creatures to live on. There are many Galaxies and highly likely that there is another planet out there that has many creatures living as innocently as us beings on planet earth, although communication would be near to impossible.
* M15 - a globular cluster near the nose of Pegasus. * NGC 7742 - a Type 2 Seyfert galaxy.
The observable Universe has at least a hundred billion galaxies. The galaxies closest to us are part of the so-called "Local Group" (that is, the group that includes our galaxy); this Local Group includes our own galaxy (i.e., the Milky Way), the Andromeda Galaxy, the Triangulum Galaxy, and about 50 dwarf galaxies such as the Large Magellanic Cloud and the Small Magellanic Cloud. Then, of course, there are hundreds or thousands of galaxies "near-by" as distances between galaxies go, but outside of our Local Group.
