NGC 718

NGC 718

NGC 718 is a spiral galaxy in the constellation Pisces about 82 million ly from Earth. It spans roughly 65,000 ly, about 65% of our Milky Way's width. It is receding from us at about 1,762 km/s.

Because its light is 82 million ly from home, you are seeing NGC 718 as it looked roughly 82 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.
