NGC 3180
The little pinwheel galaxy in Ursa Major. A face on unbarred spiral galaxy some 40 million light years away.
First discovered on the 18th of March 1787 by William Herschel. It's 2 main spiral arms are predominantly blue, which suggests mostly young hot stars inhabit them.
Many fainter more distant galaxies can be spotted in the background.
