Earth’s Internal Core Rotation May Have Paused and Perhaps Reversed

Earth's inner core. Credit: Rost-9D/iStock The rotation of the Earth's solid inner core may have recently stopped briefly as well as could be reversing, according to a study released in Nature Geoscience this week. The authors show proof that oscillation in the rotation of the internal core coincides with periodic changes in the Earth's surface...

New Outcomes Reveal Surprising Behavior of Minerals Deep in the Earth

Boudinage in brecciated dolostone rocks of the Panamint Range (Wildrose Area, Death Valley National Park). New research shows that periclase is stronger than bridgmanite in the earth's lower mantle, analogous to boudins developing in rigid ("stronger") rocks among less competent ("weaker") rocks.

The research, led by Dr. Queenie Chan from the Department of Earth Sciences at Royal Holloway, University of London, discovered organic compounds from...

Massive Volcanic Outburst Spotted on Jupiter’s Hellish Moon Io

An infrared image of Io snapped by Juno in July 2022. (NASA/JPL-Caltech/SwRI/ASI/INAF/JIRAM) The most powerful volcanic eruptions in the Solar System occur not on Earth, however on Io, a sulfurous moon orbiting the planet Jupiter. And currently, researchers from the Planetary Science Institute (PSI) in the United States have noticed a current outburst that's been surprisingly productive,...

Giant Mantle Plume Reveals Mars is More Active Than Previously Thought

Planet Mars illustration . Credit: © revers_jr / stock.adobe.com On Earth, shifting tectonic plates reshuffle the planet's surface and make for a dynamic interior, so the lack of such processes on Mars led several to think of it as a dead planet where not much occurred in the past 3 billion years. In the present problem...

Fusion Technology Is Reaching a Turning Point that Could Change the Energy Game

A donut-shaped magnetic confinement device called a tokamak is one of the leading designs for a working fusion power generator, with many such experiments running worldwide.

There Are 6 Billion Earth-Like Planets in the Milky Way Galaxy Alone, Astronomers Suggest

Credit: NASA Maybe you believe that one Earth is sufficient. However, what if the number was in the billions? According to a recent research study, the number of Earth-like planets in our Milky Way galaxy can approach 6 billion. Astronomers at the College of British Columbia (UBC) examined information from NASA's Kepler project and also came...

A Big Problem With Fusion is Solved

Since the dynamics inside a fusion reactor are extremely complicated, the walls may melt. Image credit: Max Planck Institute of Plasma physics. Cutaway of a Fusion Reactor A team of researchers from the Max Planck Institute for Plasma Physics (IPP) and the Vienna University of Technology (TU Wein) has actually found a way to manage Type-I...

Heaviest Element Yet Detected in an Exoplanet Atmosphere

Artist’s impression of an ultra-hot Jupiter transiting its star Utilizing the European Southern Observatory's Very Large Telescope (ESO's VLT), astronomers have spotted the heaviest element ever found in an exoplanet atmosphere-- barium. They were surprised to find barium at high altitudes in the atmospheres of the ultra-hot gas giants WASP-76 b and WASP-121 b-- two...
