NGC 2745

NGC 2745 is an elliptical galaxy in the constellation Cancer about 169 million ly from Earth. It spans roughly 30,000 ly, about 30% of our Milky Way's width. The light reaching us tonight left it about 169 million years ago.

Because its light is 169 million ly from home, you are seeing NGC 2745 as it looked roughly 169 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.
