NGC 2296

NGC 2296 is an elliptical galaxy in the constellation Canis Major about 129 million ly from Earth. It spans roughly 45,000 ly, about 45% of our Milky Way's width. The light reaching us tonight left it about 129 million years ago.

Because its light is 129 million ly from home, you are seeing NGC 2296 as it looked roughly 129 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.
