NGC 2976
NGC 2976, located 1° 20′ southwest of M81, is an unbarred spiral galaxy, part of the M81 group.[4] The inner structure contains many dark lanes and stellar condensations in its disk. The galaxy is sometimes classified as Sdp because its spiral arms are difficult to be traced. The bright inner part of this disk appears to have a defined edge. These distortions are results from the gravitational interactions with its neighbors.

gollark: Many people make that mistake.
gollark: I turn it off on ones with non-evil ads, which is about two.
gollark: Yes, that was a bad time. It worries me that they can remotely disable them like that, if by accident.
gollark: That way I don't need to experience the horrible suffering of still seeing ads while on my phone.
gollark: Firefox on Android supports addons, which is neat.
