NGC 3022

NGC 3022 is a lenticular galaxy in the constellation Sextans about 291 million ly from Earth. It spans roughly 140,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 291 million years ago.

Because its light is 291 million ly from home, you are seeing NGC 3022 as it looked roughly 291 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.
