IC 722

IC 722 is a barred spiral galaxy in the constellation Virgo about 305 million ly from Earth. It spans roughly 82,000 ly, about 82% of our Milky Way's width. The light reaching us tonight left it about 305 million years ago.

Because its light is 305 million ly from home, you are seeing IC 722 as it looked roughly 305 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.
