NGC 1617

NGC 1617 is a barred spiral galaxy in the constellation Dorado about 50 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 1,063 km/s.

Because its light is 50 million ly from home, you are seeing NGC 1617 as it looked roughly 50 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.
