NGC 2377

NGC 2377 is a spiral galaxy in the constellation Monoceros about 115 million ly from Earth. It spans roughly 53,000 ly, about 53% of our Milky Way's width. It is receding from us at about 2,332 km/s.

Because its light is 115 million ly from home, you are seeing NGC 2377 as it looked roughly 115 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.
