NGC 5681

NGC 5681 is a barred spiral galaxy in the constellation Boötes about 370 million ly from Earth. It spans roughly 93,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 370 million years ago.

Because its light is 370 million ly from home, you are seeing NGC 5681 as it looked roughly 370 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.
