NGC 3686
NGC 3686 is a barred spiral galaxy in the constellation Leo about 54 million ly from Earth. It spans roughly 45,000 ly, about 45% of our Milky Way's width. It is receding from us at about 1,033 km/s.

Because its light is 54 million ly from home, you are seeing NGC 3686 as it looked roughly 54 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.
