The experimental setup and test site at Store Glacier, Greenland. Researchers conceptualized a battery-powered receiver with an antenna placed on the ice that can measure ice thickness using the sun’s radio waves.

The Hikurangi Margin, located off the east coast of the North Island of New Zealand, is where the […]

ANIMATION First global assessment of the extent of snow and ice cover on Earth’s surface—a critical factor cooling the planet through reflected sunlight—and its response to warming temperatures. The global cryosphere—all of the areas with frozen water on Earth—shrank by about 87,000 square kilometers (about 33,000 square miles), a area […]

A fortuitous orbit of the International Space Station allowed the astronauts this striking view of Sarychev Volcano (Russia’s Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009.

ANIMATION Analysis of 260 million years of major geological events finds recurring clusters 27.5 million years apart. Geologic activity on Earth appears to follow a 27.5-million-year cycle, giving the planet a “pulse,” according to a new study published in the journal Geoscience Frontiers. “Many geologists believe that geological events are random over […]

An example of a chain of salps floating in the ocean.

Scientists have thought that salps […]

Stylophora pistillata, a common stony coral in the Indo-Pacific. Credit: Kevin Wyman/Rutgers University Scientists’ findings suggest corals will withstand climate change. Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how […]
