NGC 7620

NGC 7620 is a spiral galaxy in the constellation Pegasus about 446 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. It is receding from us at about 9,600 km/s.

Because its light is 446 million ly from home, you are seeing NGC 7620 as it looked roughly 446 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.
