NGC 3233

NGC 3233 is a lenticular galaxy in the constellation Hydra about 170 million ly from Earth. It spans roughly 75,000 ly, about 75% of our Milky Way's width. It is receding from us at about 3,700 km/s.

Because its light is 170 million ly from home, you are seeing NGC 3233 as it looked roughly 170 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.
