IC 84
IC 84 is a lenticular galaxy in the constellation Cetus about 233 million ly from Earth. It spans roughly 45,000 ly, about 45% of our Milky Way's width. The light reaching us tonight left it about 233 million years ago.

Because its light is 233 million ly from home, you are seeing IC 84 as it looked roughly 233 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.
