(Phys.org)—Like the solar system's telluric planets, including Earth itself, the moon's internal structure is composed of geoochemically distinct mantle, crust and core layers. The core is mostly iron; much of our understanding ...
Earth's magnetic field is crucial for our existence, as it shields the life on our planet's surface from deadly cosmic rays. It is generated by turbulent motions of liquid iron in Earth's core. Iron is a metal, which means ...

(Phys.org) —A combined team of researchers from Germany, Switzerland and the U.S. has found evidence of faster than thought core formation of planetesimals in our solar system. In their paper published in the journal Science, ...
(Phys.org) —A trio of planetary scientists from France, Switzerland and the U.K. has used seismic data, lab experiment results and theoretical calculations as a means to offer proof that oxygen is present in the Earth's ...
(Phys.org) —What happens when massive stars collapse? One potential result is a core-collapse supernova. Astronomers can make observations of such events that tell us what is happening on the surface of a star when it explodes ...

(Phys.org) —An international team of researchers has found evidence in drill core samples taken near Antarctica that adds credence to the iron fertilization hypothesis. In their paper published in the journal Science, the ...
(Phys.org) —Astronomers have peered for the first time into the heart of an exploding star in the final minutes of its existence. The feat by the high-energy X-ray satellite NuSTAR provides details of the physics of the ...

(Phys.org) —The word "core" conjures up an image of something strong. However, new experiments show that the iron found in the Earth's core is relatively weak. This finding is based on x-ray spectroscopy and diffraction ...
