NGC 418

NGC 418

NGC 418 is a spiral galaxy in the constellation Sculptor about 268 million ly from Earth. It spans roughly 150,000 ly, about 1.5 times the width of our Milky Way. It is receding from us at about 5,684 km/s.

Because its light is 268 million ly from home, you are seeing NGC 418 as it looked roughly 268 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.
