NGC 6587

NGC 6587 is an elliptical galaxy in the constellation Hercules about 146 million ly from Earth. It spans roughly 77,000 ly, about 77% of our Milky Way's width. It is receding from us at about 3,002 km/s.

Because its light is 146 million ly from home, you are seeing NGC 6587 as it looked roughly 146 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.
