NGC 2570
NGC 2570 is a spiral galaxy in the constellation Cancer about 306 million ly from Earth. It spans roughly 62,000 ly, about 62% of our Milky Way's width. The light reaching us tonight left it about 306 million years ago.

Because its light is 306 million ly from home, you are seeing NGC 2570 as it looked roughly 306 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.
