NGC 1600

NGC 1600 is an elliptical galaxy in the constellation Eridanus about 221 million ly from Earth. It spans roughly 210,000 ly, about 2.1 times the width of our Milky Way. It is receding from us at about 4,718 km/s.

Because its light is 221 million ly from home, you are seeing NGC 1600 as it looked roughly 221 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.
