NGC 722
NGC 722 is a barred spiral galaxy in the constellation Aries about 229 million ly from Earth. It spans roughly 75,000 ly, about 75% of our Milky Way's width. The light reaching us tonight left it about 229 million years ago.

Because its light is 229 million ly from home, you are seeing NGC 722 as it looked roughly 229 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.
