What if humanity could no longer live on Earth? Perhaps a catastrophic event forced us to find a new home among the stars.

NASA could one day send a fusion-powered probe to Proxima Centauri b - a potentially habitable exoplanet located just over four light years from Earth - with new research indicating the mission could ...

Researchers confirmed Wednesday there is a planet nearby that could be habitable for humans. The planet Proxima-b orbits Proxima Centauri, the closest star to our sun at just 4.2 light-years away.

Four centuries from launch, a vast spacecraft could deliver thousands of people to a world orbiting the nearest star. The concept, called Chrysalis, is designed for one purpose — to take humanity to ...

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 ...

Engineers are developing a concept for interstellar travel using a swarm of 1,000 ultra-light "laser sails." The mission aims to send these sails to Proxima b, an exoplanet 4.25 light-years away, ...

The nearest star to Earth is, of course, the sun. The nearest star system to Earth, beyond the sun, is the interesting star system known as Proxima Centauri. A red dwarf star located 4.244 light years ...

Astronomers have found nearly 6,000 exoplanets orbiting other stars. But for every confirmed detection, there are countless mere hints, inconclusive observations that could just as well be blips of ...

NASA's very productive James Webb Space Telescope (JWST) has found compelling evidence for a new planet in the Alpha Centauri star system, our closest stellar neighbor. This potential gas giant, ...

There may be a habitable world at the Sun's closest solar twin. In the complex space inhabited by the Alpha Centauri triple star system, JWST has just discerned the presence of a giant exoplanet ...
