NGC 78B
NGC 78B is a lenticular galaxy in the constellation Pisces about 255 million ly from Earth. It spans roughly 74,000 ly, about 74% of our Milky Way's width. It is receding from us at about 5,443 km/s.

Because its light is 255 million ly from home, you are seeing NGC 78B as it looked roughly 255 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.
