NGC 2139

NGC 2139 is a spiral galaxy in the constellation Lepus about 86 million ly from Earth. It spans roughly 73,000 ly, about 73% of our Milky Way's width. It is receding from us at about 1,828 km/s.

Because its light is 86 million ly from home, you are seeing NGC 2139 as it looked roughly 86 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.
