IC 183

IC 183 is a lenticular galaxy in the constellation Cetus about 182 million ly from Earth. It spans roughly 63,000 ly, about 63% of our Milky Way's width. It is receding from us at about 4,016 km/s.

Because its light is 182 million ly from home, you are seeing IC 183 as it looked roughly 182 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.
