IC 2394

IC 2394

IC 2394 is a barred spiral galaxy in the constellation Cancer about 295 million ly from Earth. It spans roughly 58,000 ly, about 58% of our Milky Way's width. The light reaching us tonight left it about 295 million years ago.

Because its light is 295 million ly from home, you are seeing IC 2394 as it looked roughly 295 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.
