NGC 3392

NGC 3392 is an elliptical galaxy in the constellation Ursa Major about 151 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 3,275 km/s.

Because its light is 151 million ly from home, you are seeing NGC 3392 as it looked roughly 151 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.
