IC 919

IC 919 is a lenticular galaxy in the constellation Ursa Major about 491 million ly from Earth. It spans roughly 77,000 ly, about 77% of our Milky Way's width. The light reaching us tonight left it about 491 million years ago.

Because its light is 491 million ly from home, you are seeing IC 919 as it looked roughly 491 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.
