NGC 6021

NGC 6021 is an elliptical galaxy in the constellation Serpens about 218 million ly from Earth. It spans roughly 98,000 ly, about the width of our Milky Way. It is receding from us at about 4,738 km/s.

Because its light is 218 million ly from home, you are seeing NGC 6021 as it looked roughly 218 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.
