NGC 1631

NGC 1631 is a lenticular galaxy in the constellation Eridanus about 436 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. It is receding from us at about 9,404 km/s.

Because its light is 436 million ly from home, you are seeing NGC 1631 as it looked roughly 436 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.
