IC 2429

IC 2429 is a spiral galaxy in the constellation Cancer about 140 million ly from Earth. It spans roughly 24,000 ly, about 24% of our Milky Way's width. It is receding from us at about 3,011 km/s.

Because its light is 140 million ly from home, you are seeing IC 2429 as it looked roughly 140 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.
