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 ...

Astronomers have used NASA's James Webb Space Telescope to find strong evidence for a planet orbiting a star in the triple system closest to our own sun. At just 4 light-years away from Earth, the ...

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 ...

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, 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 ...

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 ...

There might be a huge planet lurking near one of the closest stars to Earth. NASA's James Webb Space Telescope (JWST) has imaged a possible planet near Alpha Centauri A, a sun-like star that forms ...

The closest exoplanets to the Solar System are around the red dwarf Proxima Centauri. This little star is orbiting two bigger Sun-like stars, which are known as Alpha Centauri A and B. For over a ...

If Earth needs to borrow a cup of sugar, it's comforting to know that there may be a convenient, possibly habitable, world orbiting Alpha Centauri only 4.34 light years away – at least, if the ...

This artist’s concept shows what a gas giant orbiting Alpha Centauri A could look like. Observations of the triple star system Alpha Centauri using NASA’s James Webb Space Telescope indicate the ...

Within a few dozen light years of the Sun, the sky is crowded with stars that could, in principle, host living worlds. I want ...
