NGC 829

NGC 829 is a barred spiral galaxy in the constellation Cetus about 190 million ly from Earth. It spans roughly 65,000 ly, about 65% of our Milky Way's width. The light reaching us tonight left it about 190 million years ago.

Because its light is 190 million ly from home, you are seeing NGC 829 as it looked roughly 190 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.
