Ancient glaciers reshaped Earth’s surface and shifted ocean chemistry, fueling the rise of complex life, a new study found. Calved icebergs from the Twin Glaciers are seen in 2013 off Greenland's ...

Far below the oceans and continents we know, Earth’s deep mantle appears to have stored far more water in its early history ...

For decades, helium has been produced with natural gas, generating huge carbon emissions. Now, geologists are looking for new helium sources — and finding enormous "carbon-free" reservoirs that could ...

Abiotic chemistry in Earth’s atmosphere could have generated biologically important organosulfur molecules as life was beginning ...

Cycads use infrared heat to guide beetle pollinators, revealing an ancient plant communication system that predates flowers.

New Curtin University research has revealed how massive ancient glaciers acted like giant bulldozers, reshaping Earth's surface and paving the way for complex life to flourish. The key to unlocking ...

Scientists are uncovering signs that Earth has been hit by powerful cosmic blasts that leave little trace on the surface yet unleash extraordinary heat and pressure.

Slow orbital changes caused pulses in Earth's oxygen cycle 500 million years ago, which spurred explosions of animal life.

Scientists believe that Earth's core is a massive ball of iron. However, a new discovery suggests that the Earth's core is surrounded by an unexpected ancient structure. A high-resolution map of the ...

A new technique for measuring the Earth’s magnetic field back to the days of the dinosaurs and beyond has revealed that the magnetic field was as much as three times stronger in ancient Earth than ...

A team of researchers has made strides in understanding the formation of massif-type anorthosites, enigmatic rocks that only formed during the middle part of Earth's history. These plagioclase-rich ...

AMES, Iowa – Astronomers poring over four years of data from NASA’s Kepler spacecraft have discovered a star that’s 11.2 billion years old and has at least five Earth-size planets. “We thus show that ...
