This is a dwarf galaxy known as MCG09-20-131. Interestingly, it’s very close to us, so we can see some individual stars within it. Dwarf galaxies don’t get nearly as much attention as bigger, brighter galaxies. You might even mistake this for a local cluster of stars within our own Milky Way but at 6.5 million light years away it’s definitely not part of our galaxy. The red blob is a nebula glowing in H-alpha surrounding some bright, blue, young stars. Information obtained from the proposal for this object, here. There is some much more specific information contained in the abstract if you wish to know more.

North is NOT up. It is 28° counter-clockwise from up.
Hubble data is public domain, but I put a lot of work into combining it into beautiful color images. The minimal credit line should read: NASA / ESA / J. Schmidt
