Iron rain fell on early Earth, new Z machine data supports
Researchers at Sandia National Laboratories' Z machine have helped untangle a long-standing mystery of astrophysics: why iron is found spattered throughout Earth's mantle, the roughly 2,000-mile thick region ...
Earth's surprise inside: Geologists unlock mysteries of the planet's inner core
Seismic waves are helping scientists to plumb the world's deepest mystery: the planet's inner core.
Most of Earth's carbon may be hidden in the planet's inner core, new model suggests
As much as two-thirds of Earth's carbon may be hidden in the inner core, making it the planet's largest carbon reservoir, according to a new model that even its backers acknowledge is "provocative and speculative."
Iron 'fingerprints' point astronomers to supernova suspects
(Phys.org) —An international team of astronomers using data from the Japan-led Suzaku X-ray observatory has developed a powerful technique for analyzing supernova remnants, the expanding clouds of debris ...
Warming climates intensify greenhouse gas given out by oceans
Rising global temperatures could increase the amount of carbon dioxide naturally released by the world's oceans, fuelling further climate change, a study suggests.
Drill core evidence adds credence to iron fertilization hypothesis regarding last ice age
NuSTAR telescope takes first peek into core of supernova
(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 ...
Earth's core reveals an inner weakness
(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 ...
Iron in the Earth's core weakens before melting
The iron in the Earth's inner core weakens dramatically before it melts, explaining the unusual properties that exist in the moon-sized solid centre of our planet that have, up until now, been difficult to ...
New insights solve 300-year-old problem: The dynamics of the Earth's core
Scientists at the University of Leeds have solved a 300-year-old riddle about which direction the centre of the earth spins.
Precious Western Australia mineral geologically 'young'
Scientists at Curtin University have chronicled the genesis of a particular type of iron deposit in the state's north, finding that the valuable mineral formed relatively late in Western Australia's evolution.
Scientists solve a 14,000-year-old ocean mystery
At the end of the last Ice Age, as the world began to warm, a swath of the North Pacific Ocean came to life. During a brief pulse of biological productivity 14,000 years ago, this stretch of the sea teemed ...
Earth's iron core is surprisingly weak, researchers say
The massive ball of iron sitting at the center of Earth is not quite as "rock-solid" as has been thought, say two Stanford mineral physicists. By conducting experiments that simulate the immense pressures deep in the planet's ...
Carbon in a twirl: The science behind a self-assembled nano-carbon helix
Nanotechnology draws on the fabrication of nanostructures. Scientists have now succeeded in growing a unique carbon structure at the nanoscale that resembles a tiny twirled mustache. Their method might lead ...
