M31, The 'Great Spiral in Andromeda'
Even people without any real knowledge of astronomy have heard of 'The Andromeda Galaxy'. It has many designations....M31 and NGC224 are a couple of the duller ones, but it also goes by the title of 'The Great Spiral in Andromeda', a much more fitting name for the closest spiral galaxy to us.
At 2.5 million light years, it's just a stone's throw away in galactic
With a visual magnitude of 3.4, it's not hard to spot with the naked
eye from a reasonably dark site without the moon around.
As it's light has taken 2.5 million years to get here, it means that we are now seeing it as it was in the Lower Paleolithic period on Earth...the Dawn of Man. The first evidence of stone tools is from then. If you remember the beginning of 2001, A Space Oddyesy, that's when we're talking about.
