NGC 6808
NGC 6808 is a spiral galaxy in the constellation Pavo about 157 million ly from Earth. It spans roughly 37,000 ly, about 37% of our Milky Way's width. It is receding from us at about 3,452 km/s.

Because its light is 157 million ly from home, you are seeing NGC 6808 as it looked roughly 157 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.
