NGC 4934

NGC 4934 is a lenticular galaxy in the constellation Coma Berenices about 284 million ly from Earth. It spans roughly 83,000 ly, about 83% of our Milky Way's width. It is receding from us at about 6,093 km/s.

Because its light is 284 million ly from home, you are seeing NGC 4934 as it looked roughly 284 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.
