IC 3612

IC 3612 is a lenticular galaxy in the constellation Coma Berenices about 58 million ly from Earth. It spans roughly 18,000 ly, about 18% of our Milky Way's width. The light reaching us tonight left it about 58 million years ago.

Because its light is 58 million ly from home, you are seeing IC 3612 as it looked roughly 58 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.
