Earth’s mesosphere is often called a “no-fly zone.” The air there is far too thin for conventional aircraft. But new ultralight devices might challenge that limitation, staying aloft with nothing more than sunlight. Photophoresis as a Key to Mesosphere Flight This approach relies on photophoresis — a gas flow that occurs when light strikes an […]

Drawing inspiration from natural photosynthesis, scientists have developed a technique that uses sunlight to convert two major greenhouse gases into valuable chemicals for fuel and industrial applications. Researchers from McGill University have created a novel process called photo-driven oxygen-atom-grafting. This method employs gold, palladium, and gallium nitride as catalysts to transform carbon dioxide and methane

NASA has unveiled a high-resolution image captured by the Juno spacecraft during its recent encounter with Jupiter’s moon Io on December 30, 2023. This image not only showcases remarkable details of the volcanic satellite but also features an unusual lighting effect. During its close flyby of Io in December, the robotic Juno orbiter achieved the
