NGC 7823
NGC 7823 is a barred spiral galaxy in the constellation Tucana about 213 million ly from Earth. It spans roughly 70,000 ly, about 70% of our Milky Way's width. The light reaching us tonight left it about 213 million years ago.

Because its light is 213 million ly from home, you are seeing NGC 7823 as it looked roughly 213 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.
