IC 164
IC 164 is an elliptical galaxy in the constellation Cetus about 244 million ly from Earth. It spans roughly 110,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 244 million years ago.

Because its light is 244 million ly from home, you are seeing IC 164 as it looked roughly 244 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.
