IC 1947

IC 1947

IC 1947 is a spiral galaxy in the constellation Horologium about 538 million ly from Earth. It spans roughly 91,000 ly, about the width of our Milky Way. It is receding from us at about 9 km/s.

Because its light is 538 million ly from home, you are seeing IC 1947 as it looked roughly 538 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.
