The US Army is tripling the power on a laser cannon built to shoot down rockets, drones, and ‘more stressing threats’
The Army has decided it will no longer build a 100-kilowatt laser. Instead, it's going for a 250-300 kilowatt laser that will pack more of a punch.
A ‘spooky’ effect of physics that Einstein couldn’t believe has been photographed for the first time
The image may not look like much, but it shows a strange property of the universe called quantum entanglement.
Mysterious space objects like ‘Oumuamua will visit our solar system again. Scientists may intercept the next one with a robotic probe.
Astronomers say more interstellar objects like 'Oumuamua will visit our solar system. They hope to chase down the next one with rockets and robots.
A startup is developing a 100-gigawatt laser to propel a probe to another star system. That may be powerful enough to ‘ignite an entire city....
Breakthrough Starshot wants to use lasers to propel probes to Alpha Centauri. But chief engineer Peter Klupar said they "could ignite an entire city."
While 3D cameras such as Apple's True Depth camera can map objects that are close-by, lidar can map objects as far as 100 meters away.

A new report suggests one of the key features of the iPhone 8, which justifies its high starting price of over $1,000, is augmented reality.
NASA will soon create the coldest spot in the universe — and forge a bizarre form of matter inside it
Einstein predicted the existence of superfluids in 1924, but they're hard to study on Earth. In space, they may unlock the mysteries of gravity and dark energy
This Bill Gates-backed startup says it just knocked down one of the last things stopping drones from taking over the world
Echodyne did a successful test of a detect-and-avoid test with a drone.
