NGC 2894

NGC 2894 is a spiral galaxy in the constellation Leo about 100 million ly from Earth. It spans roughly 55,000 ly, about 55% of our Milky Way's width. The light reaching us tonight left it about 100 million years ago.

Because its light is 100 million ly from home, you are seeing NGC 2894 as it looked roughly 100 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.
