NGC 2641

NGC 2641 is a lenticular galaxy in the constellation Ursa Major about 146 million ly from Earth. It spans roughly 53,000 ly, about 53% of our Milky Way's width. The light reaching us tonight left it about 146 million years ago.

Because its light is 146 million ly from home, you are seeing NGC 2641 as it looked roughly 146 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.
