IC 3761

IC 3761 is an elliptical galaxy in the constellation Coma Berenices about 408 million ly from Earth. It spans roughly 38,000 ly, about 38% of our Milky Way's width. The light reaching us tonight left it about 408 million years ago.

Because its light is 408 million ly from home, you are seeing IC 3761 as it looked roughly 408 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.
