IC 3089

IC 3089 is an elliptical galaxy in the constellation Coma Berenices about 325 million ly from Earth. It spans roughly 69,000 ly, about 69% of our Milky Way's width. The light reaching us tonight left it about 325 million years ago.

Because its light is 325 million ly from home, you are seeing IC 3089 as it looked roughly 325 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.
