NGC 2883

NGC 2883 is an irregular galaxy in the constellation Pyxis about 54 million ly from Earth. It spans roughly 32,000 ly, about 32% of our Milky Way's width. The light reaching us tonight left it about 54 million years ago.

Because its light is 54 million ly from home, you are seeing NGC 2883 as it looked roughly 54 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.
