IC 4425
IC 4425 is a barred spiral galaxy in the constellation Boötes about 420 million ly from Earth. It spans roughly 78,000 ly, about 78% of our Milky Way's width. It is receding from us at about 9,056 km/s.

Because its light is 420 million ly from home, you are seeing IC 4425 as it looked roughly 420 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.
