IC 3317

IC 3317 is an elliptical galaxy in the constellation Coma Berenices about 922 million ly from Earth. It spans roughly 140,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 922 million years ago.

Because its light is 922 million ly from home, you are seeing IC 3317 as it looked roughly 922 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.
