There are places in the universe where gravity is on display for us all to see and this is one where we get a double dose! The larger galaxy at the top is NGC 3718. It’s got prominent streaks of dust that remind me of Centaurus A (though that isn’t visible from my latitude). If you look out on the arms you can see what look like tidal tails. It may be that those are from gravitation interactions with NGC 3729 (bottom). NGC 3718 is about 48 million light years away.

At the bottom is NGC 3729. It is about 66 million light years away. It ihas a bar structure through the center surrounded by a ring structure.

To the right of NGC 3718 is Hickson Compact Group 56. This is a group of five galaxies is about 400 million light years away and clearly show the distortions caused by gravitational interactions.

All of this is happening in a field of view about 1.5x the size of the full moon in Ursa Major.

This is 27 hours of RGB data. For the technical details, see astrobin.
