NGC 6516

NGC 6516 is a lenticular galaxy in the constellation Draco about 353 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 353 million years ago.

Because its light is 353 million ly from home, you are seeing NGC 6516 as it looked roughly 353 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.
