NGC 7810

NGC 7810 is a lenticular galaxy in the constellation Pegasus about 257 million ly from Earth. It spans roughly 72,000 ly, about 72% of our Milky Way's width. It is receding from us at about 5,532 km/s.

Because its light is 257 million ly from home, you are seeing NGC 7810 as it looked roughly 257 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.
