IC 1339

IC 1339

IC 1339 is a barred spiral galaxy in the constellation Capricornus about 393 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 8,449 km/s.

Because its light is 393 million ly from home, you are seeing IC 1339 as it looked roughly 393 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.
