Scientists have unlocked a revolutionary way to generate proton beams using high-powered lasers and a simple stream of water.

Caltech scientists are developing laser-driven lightsails that could push spacecraft beyond our solar system. Their research ...

"The lightsail will travel faster than any previous spacecraft, with potential to eventually open interstellar distances to ...

US president orders work on defence shield going beyond Ronald Reagan’s ‘Star Wars’ programme that could trigger nuclear arms ...

Amid mounting challenges to Colorado’s water supply, lawmakers are seeking to upgrade the decades-old method of tracking the ...

The idea of a lightsail comes from the fact that radiation pressure represents a mechanical pressure acting on a surface due ...

revealing how the material reacted to the laser beam. Ultimately, these findings will help develop space-ready lightsails—one of the most promising vehicles for interstellar travel, as they rely ...

Since the researchers know that a lightsail in space would not always remain perpendicular to a laser source on Earth, they next angled the laser beam to mimic this and again measured the force ...

"Chemical rockets that we use today, even with the extra speed boost from flying by planets, or from swinging by the sun for a boost, just don't have the ability to scale to useful interstellar speeds ...

China has unveiled a terrifying new weapon that could obliterate satellites with a Star Wars-style mega-beam. The ...
