A new study, published in Science Advances, has refined some important details about the moon's largest and oldest impact crater, which stretches more than 1,200 miles (2,000 km) on the far side of the moon. The new details ...
Mercury is a small, rocky planet about which researchers know relatively little. Two missions, taking readings as they passed over the planet, have revealed that Mercury is covered by an iron-poor and sulfur-rich crust. It ...

When the supercontinent Pangea began to fragment around 200 million years ago during the Early Jurassic, it reshaped the face of the planet. Vast new oceans opened, continents drifted apart and the familiar geography of today ...
Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth's crust but in our planet's mantle, the layer sandwiched between the thin crust and Earth's molten core. The new ...
