IC 2239

IC 2239 is a lenticular galaxy in the constellation Cancer about 283 million ly from Earth. It spans roughly 69,000 ly, about 69% of our Milky Way's width. It is receding from us at about 6,048 km/s.

Because its light is 283 million ly from home, you are seeing IC 2239 as it looked roughly 283 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.
