Venus may have Earth-like lithospheric thickness and heat flow
Poor old Venera 9, the Soviet Union's Venus lander, separated from its orbiter and made a hot, violent descent through the dense Venusian atmosphere on October 22, 1975, landing hard on a circular shield designed to crumple and absorb the impact. It.....»»

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......»»
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......»»
Experimental study offers insights into mysterious flow features on airless worlds
A Southwest Research Institute researcher collaborated with a team at NASA's Jet Propulsion Laboratory to attempt to explain the presence of mysterious flow features that exist on the surfaces of airless celestial bodies, such as the asteroids Vesta.....»»
Photonic computing method uses electromagnetic waves to rapidly solve partial differential equations
In the fields of physics, mathematics, and engineering, partial differential equations (PDEs) are essential for modeling various phenomena, from heat diffusion to particle motion and wave propagation. While some PDEs can be solved analytically, many.....»»
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.....»»

Ocean eddy currents funnel extreme heat and cold to the life-filled depths
On land, we're familiar with heat waves and cold snaps. But the deep sea also experiences prolonged periods of hot and cold......»»
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......»»
Lignin molecular property discovery could help turn trees into affordable, greener industrial chemicals
Trees are the most abundant natural resource living on Earth's land masses, and North Carolina State University scientists and engineers are making headway in finding ways to use them as sustainable, environmentally benign alternatives to producing i.....»»
Could injecting diamond dust into the atmosphere help cool the planet?
A multi-institutional team of climatologists, meteorologists and Earth scientists has found evidence that dropping diamond dust from an airplane into the atmosphere could cool the planet. In their study published in the journal Geophysical Research L.....»»
