NGC 1438

NGC 1438 is a spiral galaxy in the constellation Eridanus about 72 million ly from Earth. It spans roughly 42,000 ly, about 42% of our Milky Way's width. It is receding from us at about 1,524 km/s.

Because its light is 72 million ly from home, you are seeing NGC 1438 as it looked roughly 72 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.
