Interstellar materials have been identified in our Solar System, but their origin remains a mystery. A recent study suggests that the Alpha Centauri system, our stellar neighbor, could be their source ...

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 ...

The search for interstellar visitors has taken an unexpected turn. While previous discoveries like ‘Oumuamua and Comet 2I/Borisov proved that objects from beyond our solar system can pass through, new ...

The appearance of the interstellar objects (ISOs) 'Oumuamua and Comet Borisov in 2017 and 2019, respectively, created a surge of interest. What were they? Where did they come from? Unfortunately, they ...

Interstellar asteroids visiting our solar system from parts unknown used to be the stuff of science fiction. But today, we know of at least two such bodies Oumuamua and 2I/Borisov respectively ...

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 ...

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, ...

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 ...

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 ...

Centauri A and Alpha Centauri B – they are now the “best known” stars. This has also allowed a unique and very detailed comparison between “real nature” and current stellar theory for solar-type stars ...

At a distance of only 25 trillion miles, the Alpha Centauri star system is a prime target in humanity's search for life outside our Solar System. Astronomers would like to know what kind of ...
