NGC 223

NGC 223 is a lenticular galaxy in the constellation Cetus about 250 million ly from Earth. It spans roughly 86,000 ly, about the width of our Milky Way. It is receding from us at about 5,355 km/s.

Because its light is 250 million ly from home, you are seeing NGC 223 as it looked roughly 250 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.
