NGC 936

NGC 936 is a lenticular galaxy in the constellation Cetus about 57 million ly from Earth. It spans roughly 74,000 ly, about 74% of our Milky Way's width. It is receding from us at about 1,400 km/s.

Because its light is 57 million ly from home, you are seeing NGC 936 as it looked roughly 57 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.
