Fusion model hot off the wall

Heat load mitigation is critical to extending the lifetime of future fusion device. Researchers have found a way to explain the rotational temperatures measured in three different experimental fusion devices in Japan and the United States. Their model …

Breakthrough in Monte Carlo computer simulations

Researchers have developed a highly efficient method to investigate systems with long-range interactions that were previously puzzling to experts. These systems can be gases or even solid materials such as magnets whose atoms interact not only with the…

Hubble sees evaporating planet getting the hiccups

A young planet whirling around a petulant red dwarf star is changing in unpredictable ways orbit-by-orbit. It is so close to its parent star that it experiences a consistent, torrential blast of energy, which evaporates its hydrogen atmosphere — causi…

Listen to a star ‘twinkle’

Many people know that stars appear to twinkle because our atmosphere bends starlight as it travels to Earth. But stars also have an innate ‘twinkle’ — caused by rippling waves of gas on their surfaces — that is imperceptible to current Earth-bound te…
