NGC 5919

NGC 5919 is an elliptical galaxy in the constellation Serpens about 647 million ly from Earth. It spans roughly 190,000 ly, about 1.9 times the width of our Milky Way. It is receding from us at about 12,984 km/s.

Because its light is 647 million ly from home, you are seeing NGC 5919 as it looked roughly 647 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.
