NGC 6757

NGC 6757 is a lenticular galaxy in the constellation Draco about 108 million ly from Earth. It spans roughly 54,000 ly, about 54% of our Milky Way's width. The light reaching us tonight left it about 108 million years ago.

Because its light is 108 million ly from home, you are seeing NGC 6757 as it looked roughly 108 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.
