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
