IC 1346

IC 1346 is a barred spiral galaxy in the constellation Aquarius about 399 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 399 million years ago.

Because its light is 399 million ly from home, you are seeing IC 1346 as it looked roughly 399 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.
