NGC 999

NGC 999 is a spiral galaxy in the constellation Andromeda about 211 million ly from Earth. It spans roughly 48,000 ly, about 48% of our Milky Way's width. The light reaching us tonight left it about 211 million years ago.

Because its light is 211 million ly from home, you are seeing NGC 999 as it looked roughly 211 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.
