IC 5373

IC 5373 is a barred spiral galaxy in the constellation Andromeda about 464 million ly from Earth. It spans roughly 91,000 ly, about the width of our Milky Way. The light reaching us tonight left it about 464 million years ago.

Because its light is 464 million ly from home, you are seeing IC 5373 as it looked roughly 464 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.
