IC 1603
IC 1603 is a spiral galaxy in the constellation Phoenix about 370 million ly from Earth. It spans roughly 150,000 ly, about 1.5 times the width of our Milky Way. It is receding from us at about 7,962 km/s.

Because its light is 370 million ly from home, you are seeing IC 1603 as it looked roughly 370 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.
