NGC 4872

NGC 4872 is an elliptical galaxy in the constellation Coma Berenices about 335 million ly from Earth. It spans roughly 65,000 ly, about 65% of our Milky Way's width. It is receding from us at about 7,119 km/s.

Because its light is 335 million ly from home, you are seeing NGC 4872 as it looked roughly 335 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.
