NGC 3120

NGC 3120 is a spiral galaxy in the constellation Antlia about 131 million ly from Earth. It spans roughly 64,000 ly, about 64% of our Milky Way's width. It is receding from us at about 2,670 km/s.

Because its light is 131 million ly from home, you are seeing NGC 3120 as it looked roughly 131 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.
