NGC 5910 NED03

NGC 5910 NED03 is an elliptical galaxy in the constellation Serpens about 584 million ly from Earth. It spans roughly 93,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 584 million years ago.

Because its light is 584 million ly from home, you are seeing NGC 5910 NED03 as it looked roughly 584 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.
