"Solar Ash" is a graceful oasis in a platforming desert
We've strayed so far from utopia. It didn't need to be this way.In decades past, video games didn't need guns, maps filled with icons, arcane upgrade systems, or loot treadmills. They only needed platforms and a way to jump between them. I'm pretty s.....»»
Scientists discuss why we might not spot solar panel technosignatures
One of NASA's key priorities is understanding the potential for life elsewhere in the universe. NASA has not found any credible evidence of extraterrestrial life—but NASA is exploring the solar system and beyond to help us answer fundamental questi.....»»
Silicon plus perovskite solar reaches 34 percent efficiency
There are still longevity problems, but things continue to get better. Enlarge / Some solar panels, along with a diagram of a perovskite's crystal structure. (credit: Subhakitnibhat Kewiko) As the price of silicon panels.....»»
Researchers identify useful emission lines in the sun"s outer atmosphere
When studying the solar spectrum, researchers often search for specific emission lines: prominent wavelengths emitted by ions as their electrons transition from higher to lower energy levels. Emission spectra of two iron ions, Fe IX and Fe X, are par.....»»
How solar panels went from ’50s satellites to your backyard
From Einstein's theories of light to Bell Lab's revelations about doping silicon, solar power has been inching toward its current craze for more than a century. Here's how we got here......»»
Chemical and transportation industries could boost with new catalyst coating
Coupling electrochemical conversion of the greenhouse gas CO2 with renewable electricity sources—such as solar and wind—promises green production of high-demand chemicals and transportation fuels. Carbon dioxide coupling products such as ethylene.....»»
Predicting solar storms before they leave the sun
When giant solar storms hit Earth, they trigger beautiful auroral displays high in Earth's atmosphere. There's a dark side to this solar activity, though. The "space weather" it sets off also threatens our technology. The potential for damage is why.....»»
A new study shows how the sun could permanently capture rogue planets
Interest in interstellar objects (ISOs) was ignited in 2017 when 'Oumuamua flew through our solar system and made a flyby of Earth. Roughly two years later, another ISO passed through our solar system—the interstellar comet 2I/Borisov......»»
How Kepler’s 400-year-old sunspot sketches helped solve a modern mystery
A sharp decline in sunspot activity in the 17th century has long puzzled astronomers. Enlarge / A naked-eye sunspot group on May 11, 2024. There are typically 40,000 to 50,000 sunspots observed in ~11-year solar cycles. (credit:.....»»

Newly created super-black wood can improve telescopes, optical devices and consumer goods
Thanks to an accidental discovery, researchers at the University of British Columbia have created a new super-black material that absorbs almost all light, opening potential applications in fine jewelry, solar cells and precision optical devices......»»
The sun"s corona is weirdly hot, and Parker Solar Probe rules out one explanation
By diving into the sun's corona, NASA's Parker Solar Probe has ruled out S-shaped bends in the sun's magnetic field as a cause of the corona's searing temperatures, according to University of Michigan research published in The Astrophysical Journal L.....»»
Scientists now know when an ancient lake supported human life in the Namib Sand Sea
Desert regions in northern Africa and the Arabian Peninsula have been well studied by archaeologists as the home of early humans and as routes of migration along "green corridors.".....»»
Solar storms could cause more auroras on Tuesday night
Massive explosions on the sun have triggered warnings of geomagnetic storms that could create dazzling auroras in the northern United States, Europe and southern Australia on Tuesday night......»»
Study reveals the Southwest Tianshan Mountains contribute the majority of the Kyzylkum desert sand and river system
Arid Central Asia is an important dust source in the northern hemisphere, which has a significant impact on the ecological environment of Central Asia, Northwest China and even the East Asian monsoon region. The Kyzylkum Desert is one of the biggest.....»»
The New Gods of Weather Can Make Rain on Demand—or So They Want You to Believe
In a gold-trimmed command center on the outskirts of Abu Dhabi, scientists are seeking to wring moisture from desert skies. But will all their extravagant cloud-seeding tech—planes that sprinkle nanomaterials, lasers that scramble the atmosphere—.....»»
Mass breeding of desert locusts unlocks new food source
Mass breeding of desert locusts in a controlled environment could provide a sustainable source of protein for animals and humans as well as business opportunities in Sub-Saharan Africa, researchers say......»»
Dolphin cruises help Istanbul treasure its Bosphorus bottlenoses
As the first dolphin fin surfaced from the Bosphorus, a ripple of excitement went round passengers on a free boat ride to see one of Istanbul's most graceful sights......»»
US farmers want to adapt to climate change, but crop insurance won"t let them
In Kansas, where a prolonged drought has killed crops and eroded the soil, Gail Fuller's farm is like an oasis. Sheep, cows and chickens graze freely on crops and vegetation in a paradisiacal mess......»»
Why the solar corona is so much hotter than sun"s surface
In a new study published in The Astrophysical Journal, a researcher from The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, explores critical aspects of a phenomenon called kinetic Alfvén waves (KAWs) to provi.....»»
