NGC 3089

NGC 3089 is a spiral galaxy in the constellation Antlia about 123 million ly from Earth. It spans roughly 70,000 ly, about 70% of our Milky Way's width. It is receding from us at about 2,623 km/s.

Because its light is 123 million ly from home, you are seeing NGC 3089 as it looked roughly 123 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.
