By compressing iron oxide to pressures expected inside a large and rocky exoplanet, scientists discovered that such mantles could layer, mix, and flow in ways very different from those inside our planet.

Changing the way emissions are tallied may help litigators focus on the worst climate offenders and shape mitigation.


A new study confirms that an important wind system is shifting due to climate change.

A new analysis of seismic data from the Middle America Trench suggests that previous calculations have vastly overestimated the total amount of water transported to the mantle worldwide.

A new analysis suggests that a widely accepted approximation of ancient magnetic field strength may be less accurate for the past 5 million years than previously thought.

Spacecraft find that Mars oscillates 10 centimeters off its axis of rotation.


New research uses Hurricane Harvey as a case study to demonstrate the devastating power of aerosols to supercharge tropical storms.

Scientists tested whether a classic technique could detect subsurface oceans on the moons of Uranus. In this scenario, the planet’s oddball magnetic field offers a big advantage.
