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.
