NGC 7794

NGC 7794 is a spiral galaxy in the constellation Pegasus about 245 million ly from Earth. It spans roughly 83,000 ly, about 83% of our Milky Way's width. It is receding from us at about 5,264 km/s.

Because its light is 245 million ly from home, you are seeing NGC 7794 as it looked roughly 245 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.
