The sixth mass extinction—the one that seven billion humans are doing their darnedest to trigger at this very moment—is shaping up to be like nothing our planet has ever seen. That’s the conclusion of a sweeping new analysis, which compared marine fossil records from Earth’s five previous mass extinction events to what’s happening in the oceans right now.
From deep inside a Siberian mine, researchers have catalogued a series of materials unlike any others yet found in the ground. They do, however, bear a startling similarity to certain lab-grown materials that weren’t thought to exist in nature at all—until now.
Two years ago, Iceland’s Bardarbunga volcano erupted—and it kept erupting for the next 181 days, forming the largest volcanic depression ever seen. New research reveals the extraordinary processes that transpired beneath the surface, including the formation of a magma-filled canal that measured a whopping 28 miles long.
Something about the planet Mercury doesn’t sit right with astronomers: It’s too dark. Darker than the Moon, despite containing way less iron. But at long last, scientists have solved the mystery—and their discovery is shedding light on the fascinating past of the Solar System’s innermost planet.
Early last week, around 45 megatons of ice and rock plunged down the southeast flank of Mount Steele in Canada’s Yukon Territory. The avalanche, which occurred in a remote and unpopulated area, was so large that it was initially detected by earthquake seismometers.
What’s better than a stop motion explainer on asteroids, comets, meteors, and meteorites? Nothing. Nothing is better.
The Pacific Northwest is due for a continent-rending earthquake. Experts believe the odds of a Big One happening in the next half century are about one in three, the odds of a Very Big One roughly one in ten, and that, in either case, we are disastrously unprepared.
