NGC 5218

NGC 5218 is a barred spiral galaxy in the constellation Ursa Major about 135 million ly from Earth. It spans roughly 72,000 ly, about 72% of our Milky Way's width. It is receding from us at about 2,807 km/s.

Because its light is 135 million ly from home, you are seeing NGC 5218 as it looked roughly 135 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.
