IC 4021
IC 4021 is an elliptical galaxy in the constellation Coma Berenices about 267 million ly from Earth. It spans roughly 31,000 ly, about 31% of our Milky Way's width. It is receding from us at about 5,727 km/s.

Because its light is 267 million ly from home, you are seeing IC 4021 as it looked roughly 267 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.
