NGC 1686

NGC 1686 is a barred spiral galaxy in the constellation Eridanus about 266 million ly from Earth. It spans roughly 140,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 266 million years ago.

Because its light is 266 million ly from home, you are seeing NGC 1686 as it looked roughly 266 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.
