NGC 6571

NGC 6571 is an elliptical galaxy in the constellation Hercules about 222 million ly from Earth. It spans roughly 51,000 ly, about 51% of our Milky Way's width. The light reaching us tonight left it about 222 million years ago.

Because its light is 222 million ly from home, you are seeing NGC 6571 as it looked roughly 222 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.
