IC 1417

IC 1417

IC 1417 is a barred spiral galaxy in the constellation Aquarius about 252 million ly from Earth. It spans roughly 120,000 ly, about the width of our Milky Way. It is receding from us at about 5,429 km/s.

Because its light is 252 million ly from home, you are seeing IC 1417 as it looked roughly 252 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.
