NGC 504

NGC 504 is a lenticular galaxy in the constellation Pisces about 197 million ly from Earth. It spans roughly 89,000 ly, about the width of our Milky Way. It is receding from us at about 4,090 km/s.

Because its light is 197 million ly from home, you are seeing NGC 504 as it looked roughly 197 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.
