A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

NASA has successfully transmitted data between Earth and two spacecraft using lasers, completing a groundbreaking experiment that could aid in future missions to other worlds. When you purchase ...

Researchers have developed a method that could one day be used to build roads on the moon. The novel approach, described in a proof-of-concept study published in the journal Scientific Reports, would ...

Physicists are no longer content to simply listen to ripples in spacetime. A new proposal sketches out how an exquisitely tuned laser experiment could, in principle, nudge gravitational waves ...

Radiative shocks are a class of shock waves in which the transport and deposition of radiation play a central role in modulating the shock’s structure and dynamics. These phenomena are not only ...

The U.S. Naval Research Laboratory launched the Space Wireless Energy Laser Link—or SWELL—late Tuesday to demonstrate laser power beaming in space as part of a scheduled Defense Department Space Test ...
