NGC 2897

NGC 2897 is a lenticular galaxy in the constellation Hydra about 331 million ly from Earth. It spans roughly 81,000 ly, about 81% of our Milky Way's width. The light reaching us tonight left it about 331 million years ago.

Because its light is 331 million ly from home, you are seeing NGC 2897 as it looked roughly 331 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.
