IC 3637

IC 3637 is an elliptical galaxy in the constellation Coma Berenices about 94 million ly from Earth. It spans roughly 34,000 ly, about 34% of our Milky Way's width. The light reaching us tonight left it about 94 million years ago.

Because its light is 94 million ly from home, you are seeing IC 3637 as it looked roughly 94 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.
