Scientists at the European Space Agency used a laser to communicate with a spacecraft 165 million miles (265 million kilometers) away in deep space for the first time, marking a major step forward in their efforts to build optical communication systems for future missions to the Moon and beyond. Scientists at the Kryoneri Observatory near Athens, Greece, shot a powerful …

Scientists have created a penny-sized laser that they say could improve the way that autonomous vehicles can navigate the streets. The laser is intended to enhance a scientific technique called optical metrology — in which light is used to measure and identify objects. They envision several applications for their invention, including lidar (light detection and ranging), which is used to …
