Electron acceleration efficiency during the impulsive phase of a solar flare: X-ray and microwave observations
Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in magnetic reconnection events at the sun (and similar astrophysical settings) presents a major challenge in astro.....»»
Blasts from the past: New insights from old space storms
On 4 August 1972, a burst of solar plasma rocked Earth's magnetic field after hurtling through space for about 14.6 hours—the fastest sun-to-Earth plasma journey ever recorded. The resulting space storm, one of several that occurred from 2 to 11 Au.....»»
NASA begins new deployable solar array tech demo on Pathfinder spacecraft
NASA recently evaluated initial flight data and imagery from Pathfinder Technology Demonstrator-4 (PTD-4), confirming proper checkout of the spacecraft's systems including its on-board electronics as well as the payload's support systems such as the.....»»
Palo Alto Networks extends security into harsh industrial environments
The convergence of IT and operational technology (OT) and the digital transformation of OT have created new opportunities for innovation and efficiency in critical Industrial Automation and Control Systems. However, these advancements also broaden th.....»»
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.....»»
X-ray spectroscopy study maps ultrafast charge delocalization in aqueous environments
The movement of electron density is a subject of interest for chemists worldwide, as substances interact through electrons. These processes are ultrafast and traditionally require time-resolved experiments at the attosecond level to study and describ.....»»

NOAA releases imagery from world"s first operational space-based coronagraph
NOAA today shared the first images from the Compact Coronagraph (CCOR-1), a powerful solar telescope onboard the new GOES-19 satellite. CCOR-1, the world's first operational, space-based coronagraph, began observing the sun's corona, the faint outerm.....»»
Massive biodiversity data collection improves ecosystem predictions
A team at the University of Córdoba verifies that large biodiversity databases, in which citizens record observations of flora, are capable of calibrating joint species distribution models, even when conducted individually, provided that more than 5.....»»
Scientists find evidence of hellish, volcanic moon orbiting a distant exoplanet
Scientists have not yet found direct evidence of a moon outside our solar system -- but they just found a hint of a hellish one......»»
Nissan tech center volunteers cut loose after work: Wrenching, racing and learning
Doing hands-on mechanical work or driving an Acceleration Team vehicle in a race is more than just a way to have a little fun at work, team members say. It broadens their technical understanding of how cars work as well as how other teams within Niss.....»»
