NGC 2943

NGC 2943 is an elliptical galaxy in the constellation Leo about 392 million ly from Earth. It spans roughly 250,000 ly, about 2.5 times the width of our Milky Way. It is receding from us at about 8,377 km/s.

Because its light is 392 million ly from home, you are seeing NGC 2943 as it looked roughly 392 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.
