NASA will launch a box of lasers to create the coldest spot in the world


By launching an experiment to the ISS (International Space Station) on Monday, May 21st, scientists are hoping to achieve temperatures which are about a few billion times colder than vacuum present in space. It will help to analyze the atoms’ quantum behavior. CAL (Cold Atom Library) happens to be an ice-chest sized research facility. Its design and production have been carried out by the Jet Propulsion Laboratory (JPL) in California. Magnets and lasers are used to chill atom clouds present in the space station.

The launch to the space station will include numerous experiments and CAL happens to be one of them. By making use of CAL to study the quantum activity of atoms, scientists can understand better as to how the atoms will react to these extreme temperatures.

The uber-cooled atom clouds will be chilled to a temperature almost close to zero Kelvin. Such clouds are called Bose-Einstein condensates (BECs). Their atoms are so cold that they slow down. Earth’s gravitational force cannot slow down
