The Sun. It inspires songs, warms us, and grows our food. Life on land and in the oceans, the daily weather, and long-term climate patterns happen primarily because of energy we receive from our closest star. Even tiny variations in that energy can affect the workings of our planet’s atmosphere.... Read More

NASA researchers are creating a spot colder than the vacuum of space inside the International Space Station. In 2018, a new atomic refrigerator will blast off for the space station. It’s called the Cold Atom Lab (CAL), and it can refrigerate matter to one ten billionth of a degree above... Read More

When NASA astronaut Kjell Lindgren blasted off from Kazakhstan in July of 2015 for his first expedition aboard the International Space Station, he had some lofty expectations: “I was eager to see Earth from space,” he says. “And I couldn’t wait to float in microgravity,” he recalls. And … he... Read More
