IC 911

IC 911 is a barred spiral galaxy in the constellation Boötes about 447 million ly from Earth. It spans roughly 73,000 ly, about 73% of our Milky Way's width. The light reaching us tonight left it about 447 million years ago.

Because its light is 447 million ly from home, you are seeing IC 911 as it looked roughly 447 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.
