NGC 2831

NGC 2831 is an elliptical galaxy in the constellation Lynx about 239 million ly from Earth. It spans roughly 62,000 ly, about 62% of our Milky Way's width. It is receding from us at about 5,116 km/s.

Because its light is 239 million ly from home, you are seeing NGC 2831 as it looked roughly 239 million years ago. The photons left before that much of history had passed, and are only now reaching us. This distance is estimated from the galaxy's redshift, so the lookback time is approximate.
