Striking new video captures moment when Mount Etna recently erupted

New video shows the moment when Mount Etna, Europe’s largest active volcano, spewed bubbling lava and hot ash into the Sicilian sky earlier this week. On Sunday (Jan. 17), lava began “oozing” from the Etna’s southeast crater and toward the east, according to Boris Behncke, a volcanologist at the INGV-Osservatorio Etneo in Catania, Sicily, Express […]

Air pressure makes Mount Everest ‘shrink’ by thousands of feet, new study finds

Mount Everest is the tallest mountain in the world — but sometimes, it feels like the second-tallest, according to a story reported in the American Geophysical Union’s news blog Eos. That’s because the mountain’s air pressure fluctuates significantly throughout the year, a recent study found, causing the summit’s “perceived elevation” to occasionally dip below that […]

Mount Everest Can Sometimes Feel Lower Than K2

Like astronauts and master sommeliers, mountaineers who have summited Mount Everest eschewing supplemental oxygen are a rarefied group. Now, inspired by these individuals who push human physiology to its limits, researchers have analyzed the availability of oxygen on the world’s highest peak (8,848 meters). Weather-induced changes in air pressure alter the abundance of […]

There are microplastics near the top of Mount Everest too — ScienceDaily

Researchers analyzing snow and stream samples from the National Geographic and Rolex Perpetual Planet Everest Expedition have found evidence of microplastic pollution on Mount Everest. While the highest concentrations of microplastics were around Base Camp where hikers and trekkers spend the most time, the team also found microplastics as high up as 8,440 meters above […]

Microplastics are showing up in places as remote as Mount Everest

Minuscule shreds and threads of plastic are turning up all over, including in the snow on Mount Everest. “We’ve known that plastic is in the deep sea, and now it’s on the tallest mountain on Earth,” says Imogen Napper, a marine scientist at the University of Plymouth in England and a National Geographic Explorer. “It’s […]

Mount Vesuvius’ eruption turned human nerve cell tendrils to glass

Nearly 2,000 years ago, a cloud of scorching ash from Mount Vesuvius buried a young man as he lay on a wooden bed. That burning ash quickly cooled, turning some of his brain to glass. This confluence of events in A.D. 79 in the town of Herculaneum, which lay at the western base of the […]
