But the very heart of our planet remains a mystery. For many years, scientists believed that iron and nickel made up Earth’s ...

Earth formed within such a precise “Goldilocks zone” for oxygen that a 5% change would have prevented life from emerging.

Planetary scientists have discovered that high energy electrons in Earth's plasma sheet are contributing to weathering processes on the Moon's surface and, importantly, the electrons may have aided ...

The Giant Impact Hypothesis has long fascinated scientists as the leading explanation for the Moon's formation. Around 4.5 billion years ago, the Earth and a Mars-sized protoplanet called Theia ...

A colossal ocean current encircling Antarctica—stronger than all the world’s rivers combined—played a far more complex role in shaping Earth’s climate than scientists once thought. New research shows ...

A planet-forming disk with more water than all of Earth's oceans has been discovered. The disk, which is located in the constellation Taurus, is 450 light-years away from Earth. Astronomers used the ...

A new experimental study published in Geochimica et Cosmochimica Acta reveals that Mercury’s sulfur-rich interior behaves in ...

Scientists believe that gold and other precious metals are slowly leaking to the surface from Earth's core through Hawaiian ...

High-energy electrons in the Earth's plasma may be contributing to the formation of water on the surface of the moon, a study found. The findings were published by a team of researchers, led by a ...

A team of researchers, led by a University of Hawai'i (UH) at Mānoa planetary scientist, discovered that high energy electrons in Earth's plasma sheet are contributing to weathering processes on the ...
