NGC 806

NGC 806 is a barred spiral galaxy in the constellation Cetus about 182 million ly from Earth. It spans roughly 72,000 ly, about 72% of our Milky Way's width. The light reaching us tonight left it about 182 million years ago.

Because its light is 182 million ly from home, you are seeing NGC 806 as it looked roughly 182 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.
