Why is There One Long Day and one Long Night in Antarctica?
Investigate what causes Antarctica’s six-month summers and winters by studying day and cycles across the globe.
Siple's Antarctic trips are legendary. At 10, he was selected in a nationwide Boy Scout search to travel there. Several decades later, he was part of the first group to winter over at the South Pole.
Antarctica's winter runs from mid-February through late August. If you decide to stay, you're there for the duration—all aircraft traffic is stopped. Learn how research crews prepare to go it alone.
In Antarctica, the Sun never sets during the summer or rises during the winter. But do you know why? Learn the answer from a researcher who summers in the land of constant daylight.
This simple experiment eases the task of understanding daily and seasonal cycles of day and night. See firsthand why the length of daylight changes along with your location on Earth.
If the Earth turns all the way around every 24 hours, then why are some days longer than others? And why do we have winter and summer? See the answers for yourself—in a matter of seconds.
