NGC 6308

NGC 6308 is a spiral galaxy in the constellation Hercules about 411 million ly from Earth. It spans roughly 140,000 ly, about the width of our Milky Way. It is receding from us at about 8,797 km/s.

Because its light is 411 million ly from home, you are seeing NGC 6308 as it looked roughly 411 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.
