The world’s largest solar telescope and advanced computer simulations revealed vortices that are reshaping our understanding of the Sun. Across the Sun’s visible surface, hot plasma is constantly rising, cooling, and sinking. At the edges of these churning regions, researchers have now resolved tiny swirling structures that may help explain how the Sun twists, stores, [...]
Portugal vai assistir ao primeiro eclipse solar total desde 1912. Explicamos se é seguro fotografá-lo com o smartphone ou com a câmara, usando dicas de especialistas, para evitar danificar o sensor, e ferir os seus olhos.

SpaceX confirmed it will power Terafab, its $16.8 billion chip megafactory in Texas, with its own natural gas power plants and “very large battery arrays.” Tesla solar isn’t in the plan.
That’s despite Tesla being a partner on the project, and despite Tesla selling solar panels, Powerwalls, and grid-scale batteries built for exactly this kind of load.
Desenvolvida por um programador independente, a Helys usa uma fórmula científica que considera o seu tipo de pele, localização, hora do dia, condições meteorológicas e índice UV para calcular, em tempo real, quanto tempo de exposição solar é seguro e suficiente. Disponível gratuitamente apenas para iOS.

America’s 250th birthday on July 4th marked the last day to “safe harbor” a new solar project and still get the 30% solar tax credit – a milestone that many feared would mean the death of home solar. 28 days (ish) later, though, the industry is anything but dead.
The Tren Solar de la Quebrada is Latin America’s first primarily solar-powered passenger train, carrying tens of thousands of travelers through the UNESCO World Heritage-listed Quebrada de Humahuaca with the power of the sun.
Estamos a poucos dias do eclipse solar mais aguardado das últimas décadas em Portugal, e a Sun Surveyor, uma excelente ferramenta para fotógrafos, poderá ser a ferramenta perfeita para prever a posição exata do Sol e a escolher o melhor local para observar o fenómeno em segurança.

Tesla has signed a long-term deal to buy 90% of the output of Project Sterling, a big solar and battery plant going up in Arizona.
The project pairs 509 MW of solar with a 360 MW battery, and it’s being built by ContourGlobal, the power producer owned by private equity firm KKR. It’s expected online in 2028.
Tesla has signed a long-term power purchase agreement to buy the entire output of a 140-MWac solar farm being built in northeast Texas.
The plant, called Lumen Farm, is being developed by Zelestra, an EQT-backed renewable developer. Construction is expected to start in 2027, with the farm going online in 2029.
