IC 1488

IC 1488 is a spiral galaxy in the constellation Pegasus about 576 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. The light reaching us tonight left it about 576 million years ago.

Because its light is 576 million ly from home, you are seeing IC 1488 as it looked roughly 576 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.
