NGC 6635

NGC 6635 is a lenticular galaxy in the constellation Hercules about 255 million ly from Earth. It spans roughly 85,000 ly, about 85% of our Milky Way's width. It is receding from us at about 5,038 km/s.

Because its light is 255 million ly from home, you are seeing NGC 6635 as it looked roughly 255 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.
