NGC 4728

NGC 4728 is an elliptical galaxy in the constellation Coma Berenices about 299 million ly from Earth. It spans roughly 68,000 ly, about 68% of our Milky Way's width. It is receding from us at about 6,491 km/s.

Because its light is 299 million ly from home, you are seeing NGC 4728 as it looked roughly 299 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.
