IC 172

IC 172 is a barred spiral galaxy in the constellation Cetus about 381 million ly from Earth. It spans roughly 53,000 ly, about 53% of our Milky Way's width. It is receding from us at about 8,173 km/s.

Because its light is 381 million ly from home, you are seeing IC 172 as it looked roughly 381 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.
