Could alien solar panels be technosignatures?
If alien technological civilizations exist, they almost certainly use solar energy. Along with wind, it's the cleanest, most accessible form of energy, at least here on Earth. Driven by technological advances and mass production, solar energy on Eart.....»»
NASA"s heliophysics experiment to study the sun on European mission
NASA announced Tuesday it selected a new instrument to study the sun and how it creates massive solar eruptions. The agency's Joint EUV coronal Diagnostic Investigation, or JEDI, will capture images of the sun in extreme ultraviolet light, a type of.....»»
First observation of a focused plasma wave on the sun
For the first time, scientists have observed plasma waves from a solar flare focused by a coronal hole, akin to the focusing of sound waves responsible for the Rotunda effect in architecture or the focusing of light by a telescope or microscope......»»
The origin of the sun"s magnetic field could lie close to its surface
The sun's surface is a brilliant display of sunspots and flares driven by the solar magnetic field, which is internally generated through a process called dynamo action. Astrophysicists have assumed that the sun's field is generated deep within the s.....»»
The habitable worlds observatory could see lunar and solar "exo-eclipses"
A future space observatory could use exo-eclipses to tease out exomoon populations......»»
NASA tool prepares to image faraway planets
The Roman Coronagraph Instrument on NASA's Nancy Grace Roman Space Telescope will help pave the way in the search for habitable worlds outside our solar system by testing new tools that block starlight, revealing planets hidden by the glare of their.....»»
Exploring the depths: How iron snow could unlock the secrets of life on Europa
Ever since the tantalizing discovery of icy ocean worlds within our own solar system, such as Europa and Enceladus, scientists have been captivated by the possibility of life lurking beneath their frozen surfaces......»»
New quantum dot approach can enhance electrical conductivity of solar cells
A team led by Professor Jongmin Choi of the Department of Energy Science and Engineering has developed a PbS quantum dot that can rapidly enhance the electrical conductivity of solar cells. The findings are published in the journal Small......»»
Machine learning accelerates discovery of solar-cell perovskites
An EPFL research project has developed a method based on machine learning to quickly and accurately search large databases, leading to the discovery of 14 new materials for solar cells......»»
Why Earthlings are safe when huge solar storms strike our planet
When solar storms and coronal mass ejections hit Earth and create the Northern Lights, people are physically protected from radiation by Earth's magnetic field and atmosphere. From time to time, the sun discharges billions of tons of solar matt.....»»
"Danger behind the beauty": More solar storms could be heading our way
Tourists normally have to pay big money and brave cold climates for a chance to see an aurora, but last weekend many people around the world simply had to look up to see these colorful displays dance across the sky......»»
How your aurora photographs are helping NASA study solar storms
The most dramatic solar storm in decades wasn't only notable for the gorgeous colors seen in the sky -- it's also a way for scientists to learn about the sun......»»
Solar storm detected in deep sea observatories
The powerful solar storm driving the aurora borealis over global skies last weekend was also triggering the movement of compasses deep in the ocean, as revealed in new scientific findings shared today by Ocean Networks Canada (ONC), a University of V.....»»
Column: Toyota spent a bunch to build batteries. It could have spent more to make its own electricity
Toyota is spending $13.9 billion to build EV batteries in rural N.C. It should have spent more to add on-site solar, wind generation from the get-go......»»
Sun shoots out biggest solar flare in almost 2 decades, but Earth should be out of the way this time
The sun produced its biggest flare in nearly two decades Tuesday, just days after severe solar storms pummeled Earth and created dazzling northern lights in unaccustomed places......»»
Researchers develop increasingly sustainable methods for dissolving gold, silver and copper from recycled materials
Waste from computers and cell phones, solar panels and other discarded electronics are becoming an important source of noble metals alongside mining. Researchers at the University of Helsinki have developed sustainable dissolution methods for noble m.....»»
Student"s comparative analysis of primitive asteroids provides context for further research, future NASA missions
The primitive asteroids that UCF physics doctoral student Brittany Harvison studies carry with them traces of their origins and billions of years of our solar system's history......»»
NOAA says “extreme” solar storm will persist through the weekend
So far disruptions from the geomagnetic storm appear to be manageable. Enlarge / Pink lights appear in the sky above College Station, Texas. (credit: ZoeAnn Bailey) After a night of stunning auroras across much of the Un.....»»
Extreme solar storms create gorgeous views of auroras across the planet
The sun has been unusually active this week, leading to stunning views of auroras across Europe and parts of the U.S. this weekend......»»
Second night of auroras seen "extreme" solar storm
Auroras lit up skies across swaths of the planet for the second night in a row on Saturday, after already dazzling Earthlings from the United States to Tasmania to the Bahamas the day before......»»
The Northern Lights Could Be Visible Across the US Thanks to a Rare Solar Storm
Three bursts of charged particles ejected from the sun have merged into a wave that could lead to brilliant auroras being visible from Moscow to Oklahoma City......»»
