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 ...

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 ...

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 ...

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 ...

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 ...

Astronomers found strong evidence that a gassy Jupiter-size world is orbiting one of three stars in the stellar system closest to our own. By Katrina Miller Alpha Centauri has gripped the imaginations ...

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 ...

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 ...

Alpha Centauri A, on the other hand, is much more interesting from an Earth perspective. It's a G2V star similar to the Sun, which is a kind that we know can support a life-bearing planet because ...
