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 ...

A new study examines how much material from the closest star system to Earth will end up in orbit around the Sun, and how much could already be here. Reading time 2 minutes Our nearest stellar ...

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 ...

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 ...

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 ...

Researchers may have discovered a gas giant orbiting the star Alpha Centauri A, and it appears to be in the star's habitable zone. Reading time 3 minutes Exoplanet hunters have had an eye on Alpha ...

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 ...

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 ...

As Alpha Centauri moves away from its companion star, astronomers are training new instruments on the system -- hoping to catch sight of an elusive "superhabitable" planet. Share on Facebook (opens in ...
