IC 3501

IC 3501 is an elliptical galaxy in the constellation Coma Berenices about 77 million ly from Earth. It spans roughly 21,000 ly, about 21% of our Milky Way's width. The light reaching us tonight left it about 77 million years ago.

Because its light is 77 million ly from home, you are seeing IC 3501 as it looked roughly 77 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.
