NGC 2599

NGC 2599 is a spiral galaxy in the constellation Cancer about 225 million ly from Earth. It spans roughly 100,000 ly, about the width of our Milky Way. It is receding from us at about 4,690 km/s.

Because its light is 225 million ly from home, you are seeing NGC 2599 as it looked roughly 225 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.
