NGC 6643

NGC 6643 is a spiral galaxy in the constellation Draco about 69 million ly from Earth. It spans roughly 67,000 ly, about 67% of our Milky Way's width. It is receding from us at about 1,454 km/s.

Because its light is 69 million ly from home, you are seeing NGC 6643 as it looked roughly 69 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.
