IC 891

IC 891 is an elliptical galaxy in the constellation Virgo about 301 million ly from Earth. It spans roughly 68,000 ly, about 68% of our Milky Way's width. The light reaching us tonight left it about 301 million years ago.

Because its light is 301 million ly from home, you are seeing IC 891 as it looked roughly 301 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.
