NGC 7001

NGC 7001 is a spiral galaxy in the constellation Aquarius about 331 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 331 million years ago.

Because its light is 331 million ly from home, you are seeing NGC 7001 as it looked roughly 331 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.
