IC 5080

IC 5080 is an elliptical galaxy in the constellation Delphinus about 558 million ly from Earth. It spans roughly 80,000 ly, about 80% of our Milky Way's width. The light reaching us tonight left it about 558 million years ago.

Because its light is 558 million ly from home, you are seeing IC 5080 as it looked roughly 558 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.
