NGC 5875

NGC 5875 is a barred spiral galaxy in the constellation Boötes about 163 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. It is receding from us at about 3,470 km/s.

Because its light is 163 million ly from home, you are seeing NGC 5875 as it looked roughly 163 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.
