VIDEO: NASA spots change in color of Saturn’s north pole


(KRON/CNN) — NASA’s Cassini spacecraft has captured images of the changing appearance of Saturn, specifically a color change from a bluish color to a more golden hue in the planet’s north polar region since 2012.

Scientists are investigating possible reasons for the color change.

They think it could be an effect of Saturn’s seasons, particularly the increased production of photochemical hazes in the atmosphere, as the north pole approaches summer solstice next May.
