Atoms behave much differently when squeezed to pressures more than a million—or even a billion—times the atmospheric pressure on Earth. Understanding how atoms react under such high-pressure conditions can lead to the ...

The Sun-grazing asteroid, Phaethon, has betrayed its true nature by showing a comet-like tail of dust particles blown backwards by radiation pressure from the Sun. Unlike a comet, however, Phaethon's tail doesn't arise through ...
