A SpaceX Falcon 9 rocket streaks away from Launch Complex 39A at NASA’s Kennedy Space Center to begin the USSF-36 mission with the X-37B spaceplane onboard. More than eight minutes after liftoff, the first stage booster, tail number 1092, landed with a sonic boom at Landing Zone 2.

Image by Valeria Blanc / Getty Images Researchers have come up with a potentially groundbreaking — and entirely laser-free — alternative to LASIK, a popular surgical procedure that uses high-power lasers to reshape the cornea to correct vision problems. During a meeting of the American Chemical Society, a team of scientists led by Occidental College chemistry professor Michael Hill showed …

Peacock feathers are greatly admired for their bright iridescent colors, but it turns out they can also emit laser light when dyed multiple times, according to a paper published in the journal Scientific Reports. Per the authors, it’s the first example of a biolaser cavity within the animal kingdom. As previously reported, the bright iridescent colors in things like peacock …

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 …
