Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...

At roughly minus 460 F, absolute zero is abysmally cold, yet at least we can imagine it. Being only a few hundred degrees below zero, it's in the realm of something we can put our minds around. This ...

Near absolute zero, atoms stop acting like particles and start behaving like waves. In this ultracold world, scientists can ...

A large-scale array of 30,000 atoms, with a spacing of 0.5 micron, is controlled by an ultrafast laser that blinks for only 10 picoseconds. After irradiating an ultrafast laser pulse, large-scale ...

Temperature is typically thought of as the average energy of individual atoms or molecules within a given collection. For atoms of similar mass, this "kinetic temperature" would basically be their ...

The International Space Station (ISS) is slated to become the coldest spot in space as NASA's Cold Atom Laboratory (CAL) begins producing ultra-cold atoms. Called Bose-Einstein condensates, these ...
