NGC 6288

NGC 6288 is an elliptical galaxy in the constellation Draco about 478 million ly from Earth. It spans roughly 100,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 478 million years ago.

Because its light is 478 million ly from home, you are seeing NGC 6288 as it looked roughly 478 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.
