NGC 6505

NGC 6505 is an elliptical galaxy in the constellation Draco about 543 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. The light reaching us tonight left it about 543 million years ago.

Because its light is 543 million ly from home, you are seeing NGC 6505 as it looked roughly 543 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.
