NGC 451

NGC 451 is a spiral galaxy in the constellation Pisces about 230 million ly from Earth. It spans roughly 46,000 ly, about 46% of our Milky Way's width. It is receding from us at about 4,925 km/s.

Because its light is 230 million ly from home, you are seeing NGC 451 as it looked roughly 230 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.
