NGC 5712

NGC 5712 is an elliptical galaxy in the constellation Ursa Minor about 317 million ly from Earth. It spans roughly 66,000 ly, about 66% of our Milky Way's width. The light reaching us tonight left it about 317 million years ago.

Because its light is 317 million ly from home, you are seeing NGC 5712 as it looked roughly 317 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.
