NGC 811

NGC 811 is a spiral galaxy in the constellation Cetus about 89 million ly from Earth. It spans roughly 26,000 ly, about 26% of our Milky Way's width. The light reaching us tonight left it about 89 million years ago.

Because its light is 89 million ly from home, you are seeing NGC 811 as it looked roughly 89 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.
