NGC 7409

NGC 7409 is a lenticular galaxy in the constellation Pegasus about 315 million ly from Earth. It spans roughly 53,000 ly, about 53% of our Milky Way's width. The light reaching us tonight left it about 315 million years ago.

Because its light is 315 million ly from home, you are seeing NGC 7409 as it looked roughly 315 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.
