NGC 5757

NGC 5757 is a barred spiral galaxy in the constellation Libra about 128 million ly from Earth. It spans roughly 78,000 ly, about 78% of our Milky Way's width. It is receding from us at about 2,673 km/s.

Because its light is 128 million ly from home, you are seeing NGC 5757 as it looked roughly 128 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.
