While some volcanoes have spent the last 2,000 years sleeping soundly, Stromboli, a volcanic island to the north of Sicily, has taken no such rest. In fact, it’s spent nearly all of that time in an almost constant state of eruption.
Physicists have experimentally reversed electromagnetic waves in time, confirming a theoretical prediction that has stood for decades. The process, known as time reflection, causes a wave to retrace its path backward through time rather than…
By firing tiny projectiles of iron-carbon alloy from a high-speed cannon, scientists have finally demonstrated that a weird part-solid, part-liquid-like state thought to exist inside Earth’s inner core is indeed possible.
This year, the number of NASA-tracked confirmed worlds discovered beyond our solar system surpassed 6,000, and several thousand more await confirmation.
