IC 4764

IC 4764 is a spiral galaxy in the constellation Pavo about 172 million ly from Earth. It spans roughly 71,000 ly, about 71% of our Milky Way's width. It is receding from us at about 3,900 km/s.

Because its light is 172 million ly from home, you are seeing IC 4764 as it looked roughly 172 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.
