NGC 585

NGC 585 is a barred spiral galaxy in the constellation Cetus about 252 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. It is receding from us at about 5,361 km/s.

Because its light is 252 million ly from home, you are seeing NGC 585 as it looked roughly 252 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.
