IC 1347

IC 1347

IC 1347 is a lenticular galaxy in the constellation Aquarius about 410 million ly from Earth. It spans roughly 170,000 ly, about 1.7 times the width of our Milky Way. It is receding from us at about 8,730 km/s.

Because its light is 410 million ly from home, you are seeing IC 1347 as it looked roughly 410 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.
