NGC 2938

NGC 2938 is a spiral galaxy in the constellation Draco about 106 million ly from Earth. It spans roughly 38,000 ly, about 38% of our Milky Way's width. The light reaching us tonight left it about 106 million years ago.

Because its light is 106 million ly from home, you are seeing NGC 2938 as it looked roughly 106 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.
