NGC 6143

NGC 6143 is a spiral galaxy in the constellation Draco about 247 million ly from Earth. It spans roughly 79,000 ly, about 79% of our Milky Way's width. It is receding from us at about 5,235 km/s.

Because its light is 247 million ly from home, you are seeing NGC 6143 as it looked roughly 247 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.
