NGC 2566

NGC 2566 is a barred spiral galaxy in the constellation Puppis about 76 million ly from Earth. It spans roughly 88,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 76 million years ago.

Because its light is 76 million ly from home, you are seeing NGC 2566 as it looked roughly 76 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.
