Superlasers Shed Light on Super-Earth Mantles
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.
The Surprising Source of Greenhouse Gas Emissions
Changing the way emissions are tallied may help litigators focus on the worst climate offenders and shape mitigation.
Dust on the Wind
A new study confirms that an important wind system is shifting due to climate change.
Subduction May Recycle Less Water Than Thought
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.
Antarctic Lava Yields Clues to Earth’s Past Magnetic Field
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.
First Detection of a Built-In Wobble on Another Planet
Spacecraft find that Mars oscillates 10 centimeters off its axis of rotation.
To Make Better Hurricane Models, Consider Air Pollution
New research uses Hurricane Harvey as a case study to demonstrate the devastating power of aerosols to supercharge tropical storms.
Do Uranus’s Moons Have Subsurface Oceans?
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.
