NGC 7588

NGC 7588 is a lenticular galaxy in the constellation Pegasus about 507 million ly from Earth. It spans roughly 68,000 ly, about 68% of our Milky Way's width. The light reaching us tonight left it about 507 million years ago.

Because its light is 507 million ly from home, you are seeing NGC 7588 as it looked roughly 507 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.
