Researchers using ice-penetrating radar have discovered mountain ranges and valleys far beneath the ice in Antarctica. The deep valleys are hundreds of miles long, and can influence the flow of glaciers to the sea. Scientists are learning how the hidden mountains cause the East and West Antarctic ice sheets to interact with each other.

Scientists can learn a tremendous amount by taking core samples of ice, like pushing a straw into a layer cake and examining the layers in the tube. In Antarctica, scientists found an area of unbroken ice over 1,000,000 years old! The core sample will provide an amazing record of Earth’s climate, air quality, and even diseases.

Did you ever wonder how far you could travel through the ocean, in a straight line, before you hit land? If you set sail from Pakistan and never adjusted course, you’d pass between Africa and Madagascar, then between Antarctica and Tierra Del Fuego in South America, and finally end up in Russia nearly 20,000 miles later!

Kasey Stewart and Julie Berry know how to fill a 4-day weekend. They traveled to all 7 continents in 92 hours, even after a 20-hour flight delay between Chile and Antarctica due to a snowstorm! They stopped in Sydney, Dubai, Cairo, Frankfurt, Toronto, Santiago and Antarctica. Now they have to recover from extreme jetlag!

In much of the world today, it’s colder than Antarctica! Of course, maybe that’s not as impressive when you realize it’s summer there, with nearly 24 hours of daylight. The highest temperature ever recorded in Antarctica was a mild 63 degrees Fahrenheit. Antarctica’s lowest temperature was 135.8 degrees below 0, the coldest temperature ever recorded on Earth!
