NGC 7579

NGC 7579 is a galaxy in the constellation Pegasus about 574 million ly from Earth. It spans roughly 75,000 ly, about 75% of our Milky Way's width. It is receding from us at about 12,310 km/s.

Because its light is 574 million ly from home, you are seeing NGC 7579 as it looked roughly 574 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.
