NGC 3522

NGC 3522 is an elliptical galaxy in the constellation Leo about 58 million ly from Earth. It spans roughly 20,000 ly, about 20% of our Milky Way's width. It is receding from us at about 1,254 km/s.

Because its light is 58 million ly from home, you are seeing NGC 3522 as it looked roughly 58 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.
