NGC 2990

NGC 2990 is a spiral galaxy in the constellation Sextans about 144 million ly from Earth. It spans roughly 39,000 ly, about 39% of our Milky Way's width. It is receding from us at about 3,150 km/s.

Because its light is 144 million ly from home, you are seeing NGC 2990 as it looked roughly 144 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.
