IC 1940

IC 1940 is a spiral galaxy in the constellation Horologium about 636 million ly from Earth. It spans roughly 180,000 ly, about 1.8 times the width of our Milky Way. It is receding from us at about 13,640 km/s.

Because its light is 636 million ly from home, you are seeing IC 1940 as it looked roughly 636 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.
