In the quest for ever-colder temperatures, NASA is sending an apparatus to the International Space Station that will create a spot 10 billion times colder than the vacuum of space. It's called the Cold Atom Laboratory , a payload about the size of an ice chest aboard Orbital ATK's Cygnus rocket, and it will help scientists observe the weird quantum properties of ultra-cold atoms. A combination of lasers and magnets will be used to chill and slow a cloud of atoms to just a fraction above absolute zero, also known as zero Kelvin (-273.15 Celsius or -459.67 Fahrenheit). Absolute zero is the coldest temperature in the Universe - and impossible to achieve , because at that point, atoms stop moving. But the Cold Atom Laboratory (CAL) can cool clouds of atoms to just one-tenth of a billion of a degree above absolute zero, which causes them to move extremely slowly, exhibiting microscopic quantum phenomena. These clouds are called Bose-Einstein condensates. They can b
