Another first from NASA’s Juno spacecraft: the detection of radio emissions from the Moon Ganymede, over a range of about 250 kilometers in the polar region of Jupiter.Read More »Geochemistry, Mineralogy, Volcanology
Researchers suggest a magma chamber sits within an old submarine caldera structure that extends into the mantle. Nearby, a new underwater volcano emerged with a flurry of seismicity.Read More »Geology & Geophysics
The strength of Earth’s magnetic field in the distant past can tell scientists whether the planet’s magnetic poles were steady or prone to frequent reversals.Read More »Geology & Geophysics
In 2014, São Paulo experienced its greatest water crisis ever, caused by an intense drought. New research indicates that it is likely to happen again and be even more severe.Read More »Atmospheric Sciences
The diurnal variations of tropical cyclone intensification and decay are analyzed using satellite data for deep convective clouds.Read More »Geology & Geophysics
New research confirms the influence of carbon dioxide on long-term temperature trends in the upper atmosphere, but changes in Earth’s magnetic field also play a key role.Read More »Geology & Geophysics
A new analysis of long-term satellite records shows the East Antarctic Ice Sheet is unexpectedly dependent on fluctuations in weather. This study may improve models of how much sea levels will rise.Read More »Geochemistry, Mineralogy, Volcanology
The model, which will incorporate 227 million surface wave measurements, could help with everything from earthquake characterization to neutrino geosciences.Read More »
