Galaxies in our local cluster, that are gravitationally bound with the Milky-Way, do not recede with the expansion of the universe.
But then again, back when the observable universe was less than a second old, the whole enchilada was compressed into a volume a whole lot smaller than the current distance to Andromeda!
I don't get it. If like you say the galaxy was only 4 billion light years away then why did its light take 12 billion years to reach us? And how can it be 27 billion light years away when the universe is said to be only 14 billion years old?
It is all due to the expansion of the universe, and the way astronomers measure an expanding universe. If something is moving away from you, you see it where it was when the light was emitted. The expansion was so fast to begin with that all the galaxies over a certain distance away are apparently receding faster than light from our point of view.
absolutely beautiful.

Most amazing thing ever.No matter how many times I see the universe like that it always blows my mind.Also reassures me somehow

Instead of arguing who is the master of all knowledge on the comments, why you all dont take a minute of your time to contemplate and wonder?

are the Galaxy's moving faster than the speed of light?

@AlbertInSanAntonio yes they are, although they are not moving *through space* faster than light - the space is expanding!

4:37 - except the Andromeda galaxy, which is getting closer than it ever was now:P
