Earth"s Wobble Wreaks Havoc on Astronomers--And Astrologers, Too
Our planet’s precession is scarcely noticeable during anyone’s lifetime, but across history, it has had enormous effects.....»»
Seismic anisotropy in the deep mantle could partly be derived from the deformation of hydrous phase D
Shear waves split into fast and slow waves when they travel through elastically anisotropic media, and the anisotropy of the seismic velocity is recorded by seismic stations. In the Earth's deep interior, this is usually interpreted as the effect of.....»»
May 2024 super geomagnetic storm challenges current space weather prediction models
During May 2024, a series of eruption events on the sun saw the largest geomagnetic storm hit Earth in two decades. The largest since the solar storms of Halloween 2003, it occurred from May 10 to May 13, producing aurorae as far south as the Canary.....»»
New ice core data provide insight into climate "tipping points" during the last Ice Age
A changing climate triggers a sudden shift in ocean circulation, creating weather havoc and plunging Earth into an abrupt new Ice Age......»»
Observations explore the nature of stellar stream Icarus
Astronomers from Italy and Chile have investigated an accreted stellar stream named Icarus in the Milky Way's disk. Results of the study, detailed in a research paper published October 16 on the preprint server arXiv, yield crucial information regard.....»»
Photosynthesis is under threat in an increasingly warm world, says researcher
The basis of all life on Earth is photosynthesis. So, what happens if it is disrupted? Today, advanced measurement tools can reveal how climate change is affecting plants' ability to process the energy from sunlight......»»
Giant meteorite impact 3.26 billion years ago may have aided early life
Billions of years ago, long before anything resembling life as we know it existed, meteorites frequently pummeled the planet. One such space rock crashed down about 3.26 billion years ago, and even today, it's revealing secrets about Earth's past......»»
Scientists update eruption history of Oregon"s South Sister volcano
A hiker's pack usually gets lighter over time as they plow through trail mix and water, but Annika Dechert likes to joke that hers gets heavier. As an Earth sciences graduate student at the University of Oregon, she's picking up clues to the eruption.....»»
Astronomers explore the properties of an obscured hyperluminous quasar
Astronomers from the European University Cyprus and the University of Hawaii have investigated a recently discovered obscured hyperluminous quasar known as COS-87259. Results of the study, published October 14 in the Monthly Notices of the Royal Astr.....»»
Departing ISS astronaut still finds time for stunning night shot
NASA astronaut Matthew Dominick is grabbing some last-minute Earth shots from the ISS as he prepares to fly home after more than seven months in orbit......»»
Saturday Citations: Brown dwarf actually brown dwarfs; the adaptability of ice-age humans; archaeologists excited
This week, researchers discovered a near-Earth microquasar that sheds new light on sources of relativistic outflows. Doctors reported finding a triphallic gentleman. And neuroscientists reported on modest cognitive boosts from short (or "acute," in c.....»»
New research shows most space rocks crashing into Earth come from a single source
The sight of a fireball streaking across the sky brings wonder and excitement to children and adults alike. It's a reminder that Earth is part of a much larger and incredibly dynamic system......»»

MAX phases boost electrocatalytic biomass upgrading
Biomass is among the most abundant renewable resources on Earth. Through catalytic conversion, biomass can upgrade into a series of fuels and chemicals which can substitute traditional fossil resources, thus playing a crucial role in achieving the "c.....»»
A near-Earth microquasar emerges as a source of powerful radiation
Modern astronomy has clung to the belief that the relativistic outflows or jets, responsible for the existence of electromagnetic radiation of particularly high energies, are located in the nuclei of active galaxies distant from Earth. However, a dif.....»»
