A rapidly growing sunspot has fired off at least 18 M-class and three X-class flares in just 24 hours, including an intense X8.3 eruption.

Our Sun’s outer atmosphere, the corona, is millions of degrees hotter than it should be, and no one knows why.

Researchers in Malaysia designed a photovoltaic-thermal system that can be used in solar drying, space heating, rooftop systems, and off-grid thermal applications. It relies on a double-pass cooling ...

Using data collected by NASA's Parker Solar Probe during its closest approach to the sun, a University of Arizona-led ...

Their energy solutions include products for solar electric which creates and stores electricity, solar water heating—a system using evacuated tubes that allows hot water generation in cold, rainy and ...

An international research group led by Germany’s Karlsruhe Institute of Technology conducted energy, economic, and environmental assessments of 54 photovoltaic-thermal (PVT) indirect-expansion (IDX) ...

The Sun looks like a warm yellow sphere with a surface covered with glowing messy hair. The yellow glow extends to the edges of the image, with some regions brighter than others. Many bright yellow ...

Scientists have developed a way to generate electricity from Earth’s radiant heat at night, potentially powering satellites even in darkness and opening new frontiers for space renewable energy.
