NordlichReiterIs Andromeda Redshifted?

Is Andromeda Redshifted?
If our galaxy is going to collide with Andromeda, then it would probably have a blue shift, meaning it is moving towards us.
deathcowAndromeda is fun to observe in binoculars, small or large telescopes. Easy target. It is one of the few naked-eye galaxies. On a good crisp dark night you can see Andromeda just by looking up in the right place. This galaxy is so close, so big, that it appears 3 times wider than a full moon does. To the naked eye, its more like a distended smudge.
dannym3141I love the way he approaches explaining a celestial phenomenon from an angle that americans can understand. Pizza.
