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

It produces only a little power, but its innovative approach could support hardware that operates during lengthy periods of total darkness, such as deep-space satellites.

Scientists have developed a way to generate tiny amounts of solar energy at night. It’s true potential could be in space.

In general, solar PV deposited on glass is significantly more efficient than thin film, but this is the price you pay for off-world deployments. Paul Warley, CEO of Colorado-based Ascent Solar, told ...

Scientists are learning how to turn the chill of outer space into a quiet source of electricity, using the night sky itself as a heat sink. By carefully managing how surfaces shed heat after dark, ...

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 ...

A powerful flare unleashed a severe solar storm that caused auroras and GPS disruptions on Earth.

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 ...
