About ESO 137-001

The light we see from it set out 0.224 billion years ago, when the universe was 13.6 billion years old (redshift 0.0157).

The map lists it as a galaxy and shows it at the scale of the large-scale universe, drawn on the supergalactic plane.

From Wikipedia

ESO 137-001, also known as the Jellyfish Galaxy, is a barred spiral galaxy located in the constellation Triangulum Australe and in the cluster Abell 3627. As the galaxy moves to the center of the galaxy cluster at 1900 km/s, it is stripped by hot gas, thus creating a 260,000 light-year long tail.
