Mantle rocks in Papua New Guinea contain curious geochemical signatures that scientists have traditionally interpreted as evidence of billions-year-old melting. New evidence suggests otherwise.
A pandemic project analyzing a trove of infrared images revealed an unexplained phenomenon taking place in Neptune’s atmosphere.
If subduction carries hydrous minerals deep into Earth’s mantle, they may “rust” the iron outer core, forming vast sinks of oxygen that can later be returned to the atmosphere.
Helium isotopes found in water samples provide a snapshot of what lies beneath the plateau and stimulate debate within the geosciences community.
Scientists not only synthesized davemaoite but deformed it at lower mantle conditions. They found its strength and viscosity to be substantially lower than those of other minerals that make up the lower mantle.
Tree rings confirm that in northern Australia, the past 40 years have experienced more rain than any similar length of time in the past 600 years.
Los terremotos pueden liberar ráfagas de energía eléctrica que se pueden sentir en la ionosfera, a kilómetros por encima de la Tierra. Sin embargo, la teoría sigue siendo controvertida.
Extended periods of volcanism known as flood basalt eruptions lead to volcanic winters, which are often followed by an extended period of warming. But it was more than just carbon dioxide that warmed the globe.
Atmospheric winds moving at more than 7,000 kilometers per hour distort Saturn’s magnetic field, revealing why spacecraft have measured changes in the length of a day on the ringed world.
Studies since 2018 have provided competing explanations of bright radar reflections from the base of the south polar ice cap.
