NGC 7156

NGC 7156 is a spiral galaxy in the constellation Pegasus about 186 million ly from Earth. It spans roughly 76,000 ly, about 76% of our Milky Way's width. It is receding from us at about 3,954 km/s.

Because its light is 186 million ly from home, you are seeing NGC 7156 as it looked roughly 186 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.
