Powered by laser light, this tiny sail lays the groundwork for future advances in lightsail technology and the potential for ...

A team of scientists has made the first experimental measurements of laser-induced motions of miniature lightsails in the lab.

Scientists are developing miniature lightsails that could travel at unprecedented speeds, potentially enabling interstellar travel.

The ultimate goal of the lightsail project is to drive a freely accelerating lightsail that is 10 square meters in area and 100 nm or less in thickness. In this first experimental step, the Caltech ...

Researchers developed a new optical system that uses holograms to encode information, creating a level of encryption that traditional methods cannot penetrate.

Headlight glare giving you a headache? We talked to automotive experts to get the inside scoop on why cars seem brighter than ...

Finding patterns and reducing noise in large, complex datasets generated by the gravitational wave-detecting LIGO facility ...

Tractor beams using light or sound have existed for a while. Lasers can be used to create optical tweezers, a development that got Arthur Ashkin a Nobel prize in 2018 – so it is possible to move and ...

NASA tested laser communications from space with a video of a cat chasing a laser dot! Psyche beamed the video about 19 ...

We tested four super bright flashlights that range from a laser-powered flashlight that shoots a beam over a .5 mile to a ...
