M81 & M82 Again


I never get bored of these beautiful galaxies nestling themselves about 12 million light years away M81's (ngc 3031 Bodes Galaxy) A near perfect arm structure circles all the way to it's core. I can also see a 3 dimensional structure like water going down the plug hole to be swallowed up by a raging black hole of about 70 million solar masses. However only one super nova found in recent years found in 1993.

M82 (cigar galaxy ngc3034) also positions itself at the same distance. Recently well about 200 million years ago the pair were interacting resulting in a large amount of gas being funneled into its core. Also known as the starburst galaxy as it produces stars at a rate 10 times faster that our own Milky Way.

The 3rd member of the group the much smaller and fainter NGC 3077 @ mag 10.6 has a very fine wispy structure this is a result of again tidal interaction between its parents many millions of years ago.

I can also confirm a few more faint fuzzies as you can see from my labelled picture.
down to an amazing mag 15.6 Unheard of from an amateur just 10 years ago.
