IC 312

IC 312 is an elliptical galaxy in the constellation Perseus about 230 million ly from Earth. It spans roughly 80,000 ly, about 80% of our Milky Way's width. It is receding from us at about 4,835 km/s.

Because its light is 230 million ly from home, you are seeing IC 312 as it looked roughly 230 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.
