NGC 6173
NGC 6173 is an elliptical galaxy in the constellation Hercules about 410 million ly from Earth. It spans roughly 240,000 ly, about 2.4 times the width of our Milky Way. It is receding from us at about 8,771 km/s.

Because its light is 410 million ly from home, you are seeing NGC 6173 as it looked roughly 410 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.
