NGC 6023

NGC 6023 is an elliptical galaxy in the constellation Serpens about 517 million ly from Earth. It spans roughly 240,000 ly, about 2.4 times the width of our Milky Way. It is receding from us at about 11,140 km/s.

Because its light is 517 million ly from home, you are seeing NGC 6023 as it looked roughly 517 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.
