New Research Answers Lingering Questions About Siberia’s Exploding Tundra

Looking for one more reason to worry about climate change? No? Well, here’s one anyway. Rising global temperatures are causing parts of the Siberian tundra to spontaneously explode. Scientists have been studying this bizarre phenomenon since 2014, when a mysterious 165-foot-deep (50-meter-deep) hole suddenly appeared on the Yamal Peninsula in northwest Siberia. Since then, they’ve identified more than a dozen similar craters on the ​​Yamal and Gyda peninsulas and linked their formation to clima

A Meteor Impact May Have Caused a Giant Landslide in the Grand Canyon

Researchers have long puzzled over the presence of driftwood and lake sediments in Stanton’s Cave in the eastern Grand Canyon, whose mouth sits 150 feet (45.7 meters) above the river. How could the material possibly have reached that height? According to Karl Karlstrom, a geologist from the University of New Mexico, it would have had to be carried by flood levels ten times bigger than any seen in the past several thousand years. An international team of researchers proposes a surprising chain o

Astronomers Find Hidden Volcano on Mars

Mars’s marred surface consists of craters, canyons, and mysterious formations that hint at a complex geological past. Scientists recently studied a tantalizing feature that could shed light on the planet’s elusive history. A mountain perched on the rim of Mars’ Jezero Crater may actually be a volcano hiding in plain sight, according to a new study. This peak, called Jezero Mons, could offer new insight into the Red Planet’s geologic history and the potential for ancient Martian life, the resear
