NGC 6488

NGC 6488 is an elliptical galaxy in the constellation Draco about 403 million ly from Earth. It spans roughly 76,000 ly, about 76% of our Milky Way's width. The light reaching us tonight left it about 403 million years ago.

Because its light is 403 million ly from home, you are seeing NGC 6488 as it looked roughly 403 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.
