NGC 7753

NGC 7753 is a spiral galaxy in the constellation Pegasus about 242 million ly from Earth. It spans roughly 140,000 ly, about the width of our Milky Way. It is receding from us at about 5,190 km/s.

Because its light is 242 million ly from home, you are seeing NGC 7753 as it looked roughly 242 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.
