Voyager 1 Detects Plasma "Hum"
Obipale shares a report from Phys.Org: Voyager 1 -- one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space -- still works and zooms toward infinity. The craft has long since zipped past the edge o.....»»
Shrinking particle accelerators with cold plasma and a large picnic basket
Twenty-five feet below ground, SLAC National Accelerator Laboratory scientist Spencer Gessner opens a large metal picnic basket. This is not your typical picnic basket filled with cheese, bread and fruit—it contains screws, bolts, steel tubing, and.....»»
An anomalous relativistic emission arising from the intense interaction of lasers with plasma mirrors
Interactions between intense laser pulses and plasma mirrors have been the focus of several recent physics studies due to the interesting effects they produce. Experiments have revealed that these interactions can generate a non-linear physical proce.....»»
Zhurong rover detects mysterious polygons beneath the surface of Mars
China's Zhurong rover was equipped with a ground-penetrating radar system, allowing it to peer beneath Mars's surface. Researchers have announced new results from the scans of Zhurong's landing site in Utopia Planitia, saying they identified irregula.....»»
Vigil: Open-source LLM security scanner
Vigil is an open-source security scanner that detects prompt injections, jailbreaks, and other potential threats to Large Language Models (LLMs). Prompt injection arises when an attacker successfully influences an LLM using specially designed inputs......»»
LHCb: Correlations show nuances of the particle birth process
High-energy ion collisions at the Large Hadron Collider are capable of producing a quark-gluon plasma. But are heavy atomic nuclei really necessary for its formation? And above all: how are secondary particles later born from this plasma? Further clu.....»»
Telescope Array detects second-highest-energy cosmic ray ever
In 1991, the University of Utah Fly's Eye experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray's energy shocked astrophysicists. Nothing in our galaxy had the power to produce it, and th.....»»
Laser pulse compression by a density gradient plasma for exawatt to zettawatt lasers
A new method of creating laser pulses, more than 1,000 times as powerful as those currently in existence, has been proposed by scientists in the UK and South Korea......»»
JWST detects carbon dioxide in a centaur for the first time
A study published Nov. 6 in The Planetary Science Journal examines how NASA's James Webb Space Telescope (JWST) has conducted a first-time detection of carbon dioxide in a centaur, this one designated 39P/Oterma. A centaur is a small planetary body t.....»»
A new trail to exoplanets: Team successfully detects ammonia isotopologues in atmosphere of cold brown dwarf
They reveal the origin of wine, the age of bones and fossils, and they serve as diagnostic tools in medicine. Isotopes and isotopologues—molecules that differ only in the composition of their isotopes—also play an increasingly important role in a.....»»
One of the best Bluetooth headsets for work is 56% off today
The Plantronics Voyager 5200 UC Bluetooth headset, which can cancel background noise, is on sale from Amazon's Woot for an affordable $87 after a $112 discount......»»
A Personalized Brain Implant Curbed a Woman’s OCD
A device in her brain delivers jolts of electricity when it detects abnormal neural activity associated with obsessive thoughts......»»
You Asked: plasma TV replacements, cheap OLEDs, and Sharp’s return
Our resident AV expert offers advice on replacing plasma TVs, if cheap OLEDs are worth it, and the surprising return of Sharp TVs.....»»
Io has 266 active volcanic hotspots linked by a global magma ocean, finds study
Jupiter's Io stands apart from the solar system's other moons, with its numerous volcanoes and its surface dominated by lava flows. Io's surface volcanism was confirmed in 1979 when the Voyager spacecraft imaged it, but its volcanic nature isn't dupl.....»»
Astronomers capture formation of a powerful cosmic jet
Using a network of radio telescopes on Earth and in space, astronomers have captured the most detailed view ever of a jet of plasma from a supermassive black hole. The jet travels at nearly the speed of light and shows complex, twisted patterns near.....»»
NASA wants the Voyagers to age gracefully, so it’s time for a software patch
Around a half-dozen full-timers and a few part-timers are keeping Voyager alive. Enlarge / The Voyager 2 spacecraft before its launch in 1977. (credit: NASA/JPL-Caltech) Forty-six years in deep space have taken their tol.....»»
1Password detects “suspicious activity” in its internal Okta account
1Password CTO says investigation found no compromise of user data or sensitive systems. Enlarge (credit: 1Password) 1Password, a password manager used by millions of people and more than 100,000 businesses, said it detec.....»»
NASA"s Voyager team focuses on software patch, thrusters
Engineers for NASA's Voyager mission are taking steps to help make sure both spacecraft, launched in 1977, continue to explore interstellar space for years to come......»»
We landed a camera on Venus before seeing parts of our own oceans—time to ramp up observations closer to home
Viewed from the Voyager 1 space probe as it passed beyond the edge of the solar system, Earth and Venus might not look too different—same diameter, similar mass and distance from the sun......»»
NASA just launched the Psyche mission—no one knows what it will find
Psyche is going to a metal world with plasma engines and lasers. It's not sci-fi. Enlarge / A SpaceX Falcon Heavy rocket rides a column of thrust off its launch pad Friday at NASA's Kennedy Space Center in Florida. (credit: Trevo.....»»
NASA’s Psyche mission is ready for launch—no one knows what it will find
