In a discovery that challenges conventional optics, scientists have managed to make a laser beam cast its own shadow—a feat previously thought impossible, as light typically passes through other light ...

Calling the Jetbeam E28 a "flashlight" is almost a disservice, as the gizmo can pump out five different light sources and ...

It's not easy being green. Scientists for years have made small red and blue lasers, but other colors, including green, have been a challenge. A team has now filled this technology gap by creating ...

Scientists have concluded that peacocks’ tail feathers are capable of emitting narrow beams of light. A team highlighted that the colored tail feathers include tiny reflective structures that can ...

Astronomers have revealed that a Chinese satellite fired green laser beams over the state of Hawaii – at a time when tensions are boiling over between Beijing and Washington after several foreign ...

A team of scientists has found that the narrow beam of a laser, under specific conditions, can cast a shadow — a counterintuitive finding that could open the doors for new applications of optical ...

After Joint Base McGuire-Dix-Lakehurst pilot complained of a green light from the Manasquan Reservoir, Howell cops went about ...

NASA's Ice, Cloud, and Land Elevation Satellite 2, also known as ICESat-2, captured the attention of the world after Daichi Fujii, a museum curator in Japan, captured footage of the satellite's green ...

Green laser pointers have existed for 25 years, but they produce light only in a narrow spectrum of green and are not integrated in chips where they could work together with other devices to perform ...
