NGC 6911

NGC 6911

NGC 6911 is a barred spiral galaxy in the constellation Draco about 116 million ly from Earth. It spans roughly 62,000 ly, about 62% of our Milky Way's width. The light reaching us tonight left it about 116 million years ago.

Because its light is 116 million ly from home, you are seeing NGC 6911 as it looked roughly 116 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.
