As future missions look to travel back to the moon or even to Mars, new research cautions that the exposure to radiation is much higher than previously thought and could have serious implications on both astronauts and satellite technology.

Using data from NASA missions observing Earth, researchers at the University of California, Irvine have created new maps of the bed topography beneath a score of glaciers in southeast Greenland, thereby gaining a much better understanding of why some are undergoing rapid retreat and others are relatively stable.

Researchers got a rare opportunity to study an underwater volcano in the Caribbean when it erupted while they were surveying the area. The research, published online in the journal Geochemistry, Geophysics, Geosystems, a journal of the American Geophysical Union, provides new insight into the little-studied world of underwater volcanoes. It investigated a volcano named Kick-‘em-Jenny (KeJ), which is thought to be named after the turbulent waters nearby.

There’s a lot more snow piling up in the mountains of North America than anyone knew, according to a first-of-its-kind study. Scientists have revised an estimate of snow volume for the entire continent, and they’ve discovered that snow accumulation in a typical year is 50 percent higher than previously thought.

Under Mexico, where the Cocos Plate from the Pacific Ocean slides under the North American Plate, a bending line of hills, created when the seafloor first formed, sits atop a flattened area of subduction. That newly recognized combination has created a fault that likely explains last September’s Puebla earthquake, scientists report in a new study.

A new study has, for the first time, cut a clear path through a nettlesome problem: accurately measuring a powerful effect on global sea level that lingers from the last ice age. Just how quickly Earth’s deep, rocky mantle is rebounding from the heavy burden of ancient ice sheets and oceans remains somewhat uncertain. But this rebound effect, known as glacial isostatic adjustment (GIA), is critical to properly understanding the causes of sea level change.

A new study finds the fires that spread throughout North America last summer burned so powerfully their smoke pushed all the way into the stratosphere, circled the globe in roughly two weeks and remained in the stratosphere at measurable levels for several months.

A new explanation for the Moon’s origin has it forming inside the Earth when our planet was a seething, spinning cloud of vaporized rock, called a synestia.

The ocean around the Galápagos Islands has been warming since the 1970s, according to a new analysis of the natural temperature archives stored in coral reefs.

The elusive “footprint” of Jupiter’s moon Callisto has been spotted for the first time near the south pole of the giant planet, according to a new study.
