IC 3392

IC 3392 is a spiral galaxy in the constellation Coma Berenices about 78 million ly from Earth. It spans roughly 59,000 ly, about 59% of our Milky Way's width. It is receding from us at about 1,678 km/s.

Because its light is 78 million ly from home, you are seeing IC 3392 as it looked roughly 78 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.
