IC 4748

IC 4748 is a lenticular galaxy in the constellation Pavo about 209 million ly from Earth. It spans roughly 61,000 ly, about 61% of our Milky Way's width. It is receding from us at about 4,650 km/s.

Because its light is 209 million ly from home, you are seeing IC 4748 as it looked roughly 209 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.
