NGC 7808

NGC 7808 is a lenticular galaxy in the constellation Cetus about 414 million ly from Earth. It spans roughly 130,000 ly, about the width of our Milky Way. It is receding from us at about 8,923 km/s.

Because its light is 414 million ly from home, you are seeing NGC 7808 as it looked roughly 414 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.
