NGC 923

NGC 923 is a spiral galaxy in the constellation Andromeda about 266 million ly from Earth. It spans roughly 60,000 ly, about 60% of our Milky Way's width. It is receding from us at about 5,625 km/s.

Because its light is 266 million ly from home, you are seeing NGC 923 as it looked roughly 266 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.
