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 ...

A sunlike star next door called Alpha Centauri A may host a huge planet, researchers report in two studies in press in Astrophysical Journal Letters. The planet candidate orbits in its star’s ...

Using the James Webb Space Telescope (JWST), astronomers detected a potential gas giant exoplanet, designated S1, orbiting Alpha Centauri A, a star in the closest stellar system to Earth. The ...

Alpha Centauri, part of the three-star system closet to our own, is often posed in science fiction as humanity's first hop into the beyond-or perhaps its first meeting of the minds with alien ...

Recent observations from NASA’s James Webb Space Telescope revealed compelling evidence of a giant planet candidate orbiting Alpha Centauri A, a star in the nearest stellar system to the Sun. Led by ...

Just 4.3 light years from Earth lies a star called Alpha Centauri A, which is famous for being the nearest star that resembles our own Sun. In the popular Avatar movies, this star's system is home to ...

Reaching Alpha Centauri within a single human lifetime has long sounded like science fiction, yet a new generation of nuclear ...

In some of its most ambitious work yet, the James Webb Space Telescope looked to spot a planet in a potentially habitable orbit around Alpha Centauri A, the nearest sunlike star to our solar system ...

Its orbit is a bit eccentric as it revolves around Alpha Centauri A once every two or three Earth years. It's not at all likely that there's life on the planet, since it's a gas giant, but it might ...
