The light from this event has traveled 7.82 billion light-years to reach the MeerKAT radio telescope, surpassing the previous ...

Cats love laser lights. And most human families with cats also love watching their cats play with laser pointers. And let's ...

Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored ...

Back in 2000, a team of physicists led by Lijun Wang at the NEC Research Institute in Princeton, USA, pulled off a mind-bending experiment. They fired a precisely shaped laser pulse through a special ...

A new optical microresonator chip keeps light circulating longer, enhancing efficiency for next-generation sensors and ...

Researchers at the University of Basel and the ETH in Zurich have succeeded in changing the polarity of a special ferromagnet using a laser beam. In the future, this method could be used to create ...

Researchers have found that under certain conditions, a laser beam can act like an opaque object and cast a shadow, opening new possibilities for technologies that could use a laser beam to control ...

Seven beams of laser light lit up the night sky over St. Petersburg on Thursday night. It’s part of Winter Pride St. Pete, ...
