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 ...

NASA’s James Webb Space Telescope has detected strong evidence for a giant planet orbiting Alpha Centauri A, the nearest Sun-like star to Earth. Located just 4 light-years away, this possible ...

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 ...

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

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 ...
