Ultracold Gas Bubbles On  New Quantum Physics 

Space Station Revealed

While it might be a

 comfortable 72 degrees Fahrenheit (22 degrees Celsius) inside the International Space Station

There's a small chamber

 onboard where things get much, much colder — colder than space itself.

In NASA's Cold Atom Lab

 aboard the ISS, scientists have successfully blown small, spherical gas bubbles cooled to just a millionth of a degree

The test was designed to

 study how ultracold gas behaves in microgravity, and the results may lead to the fifth state of matter.

The test demonstrated that,

like liquid, gas coalesces into spheres in microgravity.

On Earth, similar experiments

have failed because gravity pulls the matter into asymmetrical droplets.
