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

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

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.

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, ...

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.

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 ...
