Pretty cool! I wonder if someone on a planet in that galaxy is looking at our galaxy in a very same way thinking how “cool is that”?
They might well. We have to look through our galactic plane at their galaxy, but the Milky Way is situated at a high angle to theirs. They would see the Milky Way approximately edge-on.
They'd need telescopes, though ... Andromeda is the nearest galaxy to ours, and to the naked eye it's just a smudge that doesn't start to get interesting until you put about a 10x glass on it.
And of course the light reaching us is Early Pliocene in age ... guys with giant space telescopes in that galaxy peering through our atmosphere might spot our ancestors lurching around the East African countryside as it was then, and strange, huge beasts wandering around -- titanotheres and things like that. Einstein will not be mocked.
