4+ day, 12+ hour ago  (716+ words) A new study has found that gas dissolving back into magma can pressurize large volcanic systems faster than gas escaping from them. That reversal accelerates the path toward eruption, tightening the window between deep recharge and surface failure. In a…...

2+ week, 1+ day ago  (1102+ words) Some volcanoes don't just erupt. They blow their tops so completely that the ground collapses into a broad crater called a caldera." These are the supervolcano systems often mentioned alongside Yellowstone and Toba. They are rare, but when they erupt,…...

1+ week, 4+ day ago  (858+ words) Saturn looks calm from a distance. A pale giant with rings, sitting quietly in space. But its surroundings tell a different story. The space around the planet is busy, charged, and constantly shifting. New research shows that Saturn's magnetic shield,…...

18+ hour, 53+ min ago  (729+ words) A volcano that can change the climate of the entire planet sounds like something from a movie. But supereruptions are real, and Earth has experienced them before. Scientists continue to study these powerful events to understand how such massive eruptions…...

4+ day, 16+ hour ago  (910+ words) Researchers have discovered that complex animals appear in fossils dating to before the Cambrian explosion, a period about 538 million years ago when most major animal groups first show up in the fossil record. The findings include some of the oldest…...

1+ week, 1+ day ago  (857+ words) Scientists have confirmed that a tiny Triassic fossil long mistaken for another animal is actually its own species. That shift turns a long-standing misidentification into evidence of a much older lineage that survived a mass extinction. A small skull discovered…...

1+ week, 2+ day ago  (681+ words) Life on Earth began from very simple things. Long before plants, animals, or even tiny microbes existed, the planet only had water, rocks, and basic chemicals. Over time, these simple ingredients somehow came together to form life. Scientists are still…...

1+ week, 3+ day ago  (838+ words) Scientists have found that microbes inside a dead ichthyosaur, an extinct marine reptile that lived during the age of dinosaurs, actively created the mineral structure that preserved its skeleton in three dimensions. That result reframes fossilization as a process shaped…...

1+ week, 4+ day ago  (805+ words) Scientists have found that a long-mysterious rumble beneath Mount Etna, an active volcano on the Italian island of Sicily, is made up of surface-traveling waves rather than deeper, chaotic seismic noise. That realization explains why earlier readings kept pointing in…...

1+ week, 4+ day ago  (854+ words) Astronomers can now rule out much of what a suspected pair of supermassive black holes in a distant galaxy could look like, even though they have not yet confirmed they exist. That finding keeps the long-suspected "black hole binary" system…...
