NGC 518

NGC 518 is a spiral galaxy in the constellation Pisces about 126 million ly from Earth. It spans roughly 57,000 ly, about 57% of our Milky Way's width. It is receding from us at about 2,704 km/s.

Because its light is 126 million ly from home, you are seeing NGC 518 as it looked roughly 126 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.
