One million alien visitors from another star system could already be lurking in the solar system. We aren't talking about "little green men" here, however — more "little (and not so little) gray rocks ...

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 ...

A giant planet may be orbiting the nearest Sun-like star to Earth, and the discovery is sparking excitement across the astronomy world. Using the James Webb Space Telescope, researchers have detected ...

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 ...

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 ...

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 ...

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

The recent discovery of a potential gas giant circling the nearby star Alpha Centauri A has led to speculation that it may be orbited in turn by a habitable moon that could support life, just like in ...
