Record-breaking metalens could revolutionize optical technologies

Traditional lenses—like the ones found in eyeglasses—are bulky, heavy and only focus light across a limited number of wavelengths. A new, ultrathin metalens developed by researchers at the University of California, Berkeley, ...

Solar energy tracker powers down after 17 years

After nearly two decades, the Sun has set for NASA's SOlar Radiation and Climate Experiment (SORCE), a mission that continued and advanced the agency's 40-year record of measuring solar irradiance and studying its influence ...

Mercury's 400 C heat may help it make its own ice

It is already hard to believe that there is ice on Mercury, where daytime temperatures reach 400 degrees Celsius, or 750 degrees Fahrenheit. Now an upcoming study says that the Vulcan heat on the planet closest to the sun ...

Biological material boosts solar cell performance

Next-generation solar cells that mimic photosynthesis with biological material may give new meaning to the term "green technology." Adding the protein bacteriorhodopsin (bR) to perovskite solar cells boosted the efficiency ...

Sun science has a bright future on the moon

There are many reasons NASA is pursuing the Artemis mission to land astronauts on the moon by 2024: It's a crucial way to study the moon itself and to pave a safe path to Mars. But it's also a great place to learn more about ...
