NGC 3736

NGC 3736 is a barred spiral galaxy in the constellation Draco about 595 million ly from Earth. It spans roughly 200,000 ly, about 2.0 times the width of our Milky Way. The light reaching us tonight left it about 595 million years ago.

Because its light is 595 million ly from home, you are seeing NGC 3736 as it looked roughly 595 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.
