IC 4751

IC 4751 is a lenticular galaxy in the constellation Pavo about 211 million ly from Earth. It spans roughly 66,000 ly, about 66% of our Milky Way's width. It is receding from us at about 4,800 km/s.

Because its light is 211 million ly from home, you are seeing IC 4751 as it looked roughly 211 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.
