NGC 3012

NGC 3012 is an elliptical galaxy in the constellation Leo Minor about 541 million ly from Earth. It spans roughly 200,000 ly, about 2.0 times the width of our Milky Way. The light reaching us tonight left it about 541 million years ago.

Because its light is 541 million ly from home, you are seeing NGC 3012 as it looked roughly 541 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.
