7+ mon, 1+ week ago   (869+ words) Earth’s deepest center keeps moving, and the motion is more complicated than scientists once assumed. Hidden thousands of miles beneath the surface, the planet’s inner core is inaccessible to direct observation, leaving researchers to infer its behavior from seismic signals....

7+ mon, 3+ week ago   (826+ words) Deep beneath our feet, Earth’s core may be far less rigid than scientists once believed. A new laboratory result suggests the planet’s innermost region can behave as both solid and subtly mobile, reshaping how its deepest structure is understood. In…...

7+ mon, 3+ week ago   (822+ words) Deep beneath the planet’s surface, Earth’s core behaves in a way scientists have struggled to explain for decades, with consequences for how the planet moves and protects itself. New evidence now suggests that the solid heart of Earth is softer…...

8+ mon, 3+ week ago   (1029+ words) New experiments suggest that Earth’s deep mantle, the hot rocky layer far below, once stored enough water in rock to equal one ocean. By squeezing and heating samples to deep-mantle conditions, scientists in Guangzhou, China, traced how water moved into…...

8+ mon, 4+ week ago   (785+ words) For about 540 million years, Earth’s magnetic field and the oxygen in its air have risen and fallen together. A NASA-led team has now measured that link, suggesting the planet’s molten core helped create the long-term conditions necessary for complex life…...

9+ mon, 2+ week ago   (992+ words) About 1,800 miles (2,900 kilometers) below our feet, two enormous patches of strange rock sit above Earth’s core. New computer models now tie these deep structures to slow chemical leaks between the core and mantle that may have helped Earth stay habitable....

10+ mon, 1+ week ago   (794+ words) A 100-year-old idea about what props up the Himalayas is being replaced by a new model. It proposes that a rigid slice of mantle, wedged between Asian and Indian crust, helps hold up the Himalayas, also known as the roof…...
