IC 5091

IC 5091 is a spiral galaxy in the constellation Pavo about 800 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 800 million years ago.

Because its light is 800 million ly from home, you are seeing IC 5091 as it looked roughly 800 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.
