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 ...

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

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 ...

Three increasingly close views from NASA’s Webb show how a possible planet was revealed in the Alpha Centauri triple star system. A coronagraphic mask placed over one of the system’s two Sun-like ...

A team of astronomers on Thursday provided the strongest evidence yet that a planet circles one of Alpha Centauri’s sunlike stars. The world is at the very edge of the region around the star where ...

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 ...

In humanity's search for life outside our Solar System, one of the best places to look is Alpha Centauri, a system containing the three nearest stars beyond the Sun. A new study that has involved ...

How close to Earth could we find the next Earth-like exoplanet? This is what two papers accepted in The Astrophysical Journal Letters hopes to address as a team of more than two dozen researchers ...

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

NASA's very productive James Webb Space Telescope (JWST) has found compelling evidence for a new planet in the Alpha Centauri star system, our closest stellar neighbor. This potential gas giant, ...
