IC 4906

IC 4906 is an elliptical galaxy in the constellation Pavo about 175 million ly from Earth. It spans roughly 82,000 ly, about 82% of our Milky Way's width. It is receding from us at about 3,766 km/s.

Because its light is 175 million ly from home, you are seeing IC 4906 as it looked roughly 175 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.
