Induction heating can completely change the energy budget of an exoplanet and even melt its interior. In a study published by Nature Astronomy an international team led by the Space Research Institute of the Austrian Academy of Sciences with participation of the University of Vienna explains how magma oceans can form under the surface of exoplanets as a result of induction heating.
Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change.
Explosive volcanic eruptions in the tropics can lead to El Niño events, those notorious warming periods in the Pacific Ocean with dramatic global impacts on the climate, according to a new study.
A team of scientists has found new evidence that the Great Permian Extinction, which occurred approximately 250 million years ago, was caused by massive volcanic eruptions that led to significant environmental changes.
New research led by the University of Delaware resolves debate over the strength of olivine, the most abundant mineral in the Earth's mantle. Measuring olivine’s strength is critical to understanding how strong tectonic plates are, which matters to how plates break and create subduction zones.
East Africa may be a long way from the Crescent City but it is top of mind for Tulane PhD student Sarah Oliva, who is studying data from volcanoes and earthquakes in that region. Her goal is a better understanding of how a 3,000-kilometer long deep valley– the East African rift system— formed. Ultimately, she hopes her research will enable her to work with scientists and help governments protect residents living near the rift.
New research, led by the University of Southampton and involving a team of international scientists, suggests that an extreme global warming event 56 million years ago was driven by massive CO2 emissions from volcanoes, during the formation of the North Atlantic Ocean.
New research from the University of New Hampshire has led to the development of a novel technique to determine the surface area and volume of small particles, the size of a grain of sand or smaller. Due to their tiny size, irregular shape and limited viewing angle, commonly used microscopic imaging techniques cannot always capture the whole object’s shape often leaving out valuable information that can be important in numerous areas of science, engineering and medicine.
A new look inside 2,000-year-old Roman concrete has provided new clues to the evolving chemistry and mineral cements that allow ancient harbor structures to withstand the test of time.
ASU scientists develop technique to trace volcano heat pulses; may help better predict risk
The classic red teardrop of magma underneath a volcano peak is too simplistic. Magma chambers are chemically and physically complex structures that new evidence, published this week in Science, suggests may be cooler and more solid than expected.
The discovery of anomalously high levels of mercury in rocks from the Ordivician geological period has led to a new interpretation of the ensuing mass extinction. A sequence of disturbances may have led to catastrophic cooling by reflective sulfate aerosols injected into the atmosphere by massive volcanism. The finding is important since aerosol cooling is under consideration as a way to temper global warming.
Experiments at Berkeley Lab’s Advanced Light Source have helped scientists to solve a mystery of why some rocks can float for years in the ocean, traveling thousands of miles before sinking.
Researchers led by the Virginia Tech College of Science discovered that deep portions of Earth’s mantle might be as hot as it was more than 2.5 billion years ago.
University of Iowa volcanologist Ingrid Ukstins spent two weeks collecting samples from Yasur, a continuously erupting volcano on Tanna, an island in the remote South Pacific archipelago of Vanuatu, to study its chemical composition and determine how the gasses it produces may be affecting people who live nearby.
A number of volcanoes around the world continuously exhale gases. Of these, sulfur dioxide is the easiest to detect from space and now researchers have created the first global map of SO2 plumes from volcanoes.
As planning continues for humanity’s first visit to Mars, scientists still have much to learn about the planet’s physical makeup. By comparing current satellite images to similar shots of Earth, they are coming to understand how volcanic activity shaped the Red Planet, and extrapolating lessons learned to address concerns closer to home.
Holidaymakers concerned about fresh volcanic eruptions causing flight-disrupting ash clouds across Northern Europe might be reassured by a study setting out the first reliable estimates of their frequency
The island of Madagascar off the coast of Africa was largely unexplored seismically until recently. The first broadband seismic images of the island help solve a longstanding mystery: why are there volcanoes far from any tectonic boundary?
