NGC 496

NGC 496 is a barred spiral galaxy in the constellation Pisces about 283 million ly from Earth. It spans roughly 73,000 ly, about 73% of our Milky Way's width. The light reaching us tonight left it about 283 million years ago.

Because its light is 283 million ly from home, you are seeing NGC 496 as it looked roughly 283 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.
