NGC 6166

NGC 6166 is an elliptical galaxy in the constellation Hercules about 436 million ly from Earth. It spans roughly 270,000 ly, about 2.7 times the width of our Milky Way. It is receding from us at about 9,100 km/s.

Because its light is 436 million ly from home, you are seeing NGC 6166 as it looked roughly 436 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.
