IC 3448

IC 3448 is an elliptical galaxy in the constellation Coma Berenices about 64 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 64 million years ago.

Because its light is 64 million ly from home, you are seeing IC 3448 as it looked roughly 64 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.
