IC 601
IC 601 is a spiral galaxy in the constellation Leo about 170 million ly from Earth. It spans roughly 23,000 ly, about 23% of our Milky Way's width. It is receding from us at about 3,672 km/s.

Because its light is 170 million ly from home, you are seeing IC 601 as it looked roughly 170 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.
