A team of researchers from Texas A&M University has demonstrated the use of laser beams to lift and steer tiny engineered ...

Using even the most advanced rocket propulsion technologies available today, it would take billions ...

A chip-sized structure made of silicon nanopillars floated off a surface inside a Cornell University lab, pushed upward by ...

Alpha Centauri, the nearest star system to our own, sits 4.37 light-years away. At the speed Voyager 1 travels, reaching it ...

Since Star Trek was beamed into our television sets in 1966, warp drives and faster-than-light engines have been the pillar ...

Getting a spacecraft to another star is a monumental challenge. However, that doesn't stop people from working on it. The most visible groups currently doing so are Breakthrough Starshot and the Tau ...

Laser sail propulsion is an idea that won't go away. By aiming powerful Earth-based lasers at tiny spacecraft with light sails, tiny spacecraft can be accelerated to near-relativistic speeds without ...

Alpha Centauri, one of the two "Pointer Stars" that help stargazers find the Southern Cross in the Southern Hemisphere, may have a planet in orbit around it. If it does, the Webb Telescope will find ...

One million alien visitors from another star system could already be lurking in the solar system. We aren't talking about "little green men" here, however — more "little (and not so little) gray rocks ...
