NGC 4089

NGC 4089 is an elliptical galaxy in the constellation Coma Berenices about 337 million ly from Earth. It spans roughly 84,000 ly, about 84% of our Milky Way's width. It is receding from us at about 6,962 km/s.

Because its light is 337 million ly from home, you are seeing NGC 4089 as it looked roughly 337 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.
