New research connects a powerful volcanic eruption—and a medieval poem that conjured memories of the dreaded event—to Iceland’s conversion to Christianity.

Diamonds, the super-strong and brilliant crystals of carbon atoms produced under the Earth’s crushing pressures, are typically valued for their beauty and durability. But scientists also value them for another reason: They contain all kinds of hidden messages about the Earth’s mantle. You just need the right tools to…

Perhaps there’s a life-supporting, Earth-like planet orbiting close to a red dwarf star many light years away. Perhaps this planet orbits so close to the star that only one half of it ever faces the light. Maybe some sentient species evolved during that infinite day, on some massive supercontinent. And maybe one day,…

For hundreds of millions of years, life on Earth was a purely aquatic phenomenon. The jump from the oceans to the continents was a monumental event, one that would irrevocably change the face of our plant. A new study suggests the first plants to make this evolutionary leap appeared much earlier than we thought.

A powerful earthquake struck Taiwan today, causing damage and a partially collapsed hotel building, sources report.

It’s not often that science can answer questions with an easy “yes” or “no.” Usually it’s more of an “evidence suggests” or “this correlation proposes” sort of situation, even if the public’s understanding is generally a little less nuanced. So USGS Seismologist Susan Hough found the right question:

Slow waves meander westward out in the deep ocean south of Australia. Sometimes they carry with them carry large eddies, whirlpools over 100 miles across. But every so often, these whirlpools combine into double whirlpools and travel across the ocean 10 times faster than the rest of the whirlpools, moving in sync for…

Lasciate ogni speranza, voi ch’entrate, reads the gates to the Inferno. “Abandon all hope, you who enter,” which is a pretty nice way of saying “welcome to Hell.” But there’s a real underworld, albeit one with fewer dogs and less being blown around by the wind or wading through shit. Scientists are working on a…

The largest mud volcano eruption has been raging in Indonesia since May 29, 2006. At its peak, 180,000 cubic meters of mud flowed daily from a site near a heavily populated region of Java—enough mud to completely fill the Empire State Building every six days. Almost 60,000 villagers have fled since then, and it’s…

If you made a building out of bricks and cinderblocks, then hundreds of years later you’d expect it to still be, well, a building made of bricks and cinderblocks. But planets are not buildings if you haven’t noticed. Earth, for instance, just doesn’t seem to have the same composition as the meteors thought to have…

In news that is sure to vindicate chemtrail truthers, NASA has finally delivered on its longstanding promise to produce a dazzling display of artificial clouds. And dang, was it cool.

Xenon is a peculiar element. It certainly has one of the most mysterious names (from the Greek xenos, or “stranger”). As a noble gas, it refuses to bond with other elements except under exotic conditions. And its uses are all about as creepy as its name: Folks use it for its eerie glow, to detect radiation, or in its…

In a dramatic development, the giant rift in the Larsen C ice shelf has grown an additional 11 miles (17 km) since last week, and the leading tip of the crack is now exceptionally close to the ocean. There’s now very little to prevent a complete collapse—an event that will produce one of the largest icebergs in…
