An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships. It's a goal that sounds so fantastic, you'd be forgiven ...

Powered by laser light, this tiny sail lays the groundwork for future advances in lightsail technology and the potential for ...

"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 ...

Tiny spaceships could be accelerated by lasers so that they reach the nearest star in 20 years. That's the theory. Now it's ...

A team of scientists has made the first experimental measurements of laser-induced motions of miniature lightsails in the lab.
