Sapphires are among the most precious gems, yet they consist solely of chemically 'contaminated' aluminum oxide, or corundum. It is widely assumed that these crystals with their characteristically ...

Some scientists think we can better understand volcanoes by learning how the gaseous vortexes emerge. By Carolyn Wilke Some volcanoes perform a rather subtle trick: blowing rings of vapor that waft ...

Some volcanoes, such as the Cascade volcanoes up in Washington and Oregon, are of the type called a stratovolcano. These steep volcanoes sometimes erupt explosively and other times have calmer lava ...

The moon could contain massive slabs of ice at its north and south poles formed from the steam of vast ancient volcanoes, according to new research. If the new predictions are correct, it opens up the ...

Iron particles, from meteorites or volcanic ash, could have catalyzed the chemical reactions that formed the building blocks of life over four billion years ago on Earth, a new study suggests. The ...

Scientists have long wondered how volcanoes formed in central Anatolia despite being far from tectonic plate borders—now they've found evidence of a hot plume of magma flowing from East Africa. Riders ...

Unusual molten rock formations, nicknamed lava eggs, have appeared near an active volcano in Iceland. Some were recently spotted by a geologist, who explained to Reuters how the egg-shaped lobes ...

These ghostly hoops have been spotted above volcanic events around the world. But how they form has long been a mystery. Mount Etna—located in Catania, Italy—is one of the rare volcanoes that can blow ...

In a science lab on the fourth floor of UTSA's Multidisciplinary Studies Building, UTSA students engage in meticulous ...

Images of Pluto captured by NASA's New Horizons mission have revealed a new surprise: ice volcanoes. The spacecraft performed a flyby of the dwarf planet and its moons in July 2015, and the insights ...
