IC 3686

IC 3686 is a spiral galaxy in the constellation Virgo about 943 million ly from Earth. It spans roughly 230,000 ly, about 2.3 times the width of our Milky Way. The light reaching us tonight left it about 943 million years ago.

Because its light is 943 million ly from home, you are seeing IC 3686 as it looked roughly 943 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.
