NGC 6007

NGC 6007 is a spiral galaxy in the constellation Serpens about 491 million ly from Earth. It spans roughly 220,000 ly, about 2.2 times the width of our Milky Way. It is receding from us at about 10,487 km/s.

Because its light is 491 million ly from home, you are seeing NGC 6007 as it looked roughly 491 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.
