NGC 7421
NGC 7421 is a barred spiral galaxy in the constellation Grus about 84 million ly from Earth. It spans roughly 58,000 ly, about 58% of our Milky Way's width. It is receding from us at about 1,830 km/s.

Because its light is 84 million ly from home, you are seeing NGC 7421 as it looked roughly 84 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.
