NGC 216

NGC 216

NGC 216 is a lenticular galaxy in the constellation Cetus about 74 million ly from Earth. It spans roughly 29,000 ly, about 29% of our Milky Way's width. It is receding from us at about 1,573 km/s.

Because its light is 74 million ly from home, you are seeing NGC 216 as it looked roughly 74 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.
