We aren't talking about "little green men" here, however — more "little (and not so little) gray rocks," asteroids from the triple star system Alpha Centauri. Alpha Centauri is the closest star ...

This means that despite Alpha Centauri being a mature system, its complex gravitational dynamics still result in the ejection of material that can potentially reach our solar system. The presence ...

Consequently, even though it is one of the closest stars to Earth, such that its light takes only six years to get here, it ...

Alpha Centauri is the star system closest to our Solar System, and it is likely that particles from it could be making their way over to or already be in our stellar neighborhood. To know what to ...

Alpha Centauri is also moving towards us ... much as asteroids or comets are currently being ejected from our solar system," the researchers wrote in the study. In fact, the astronomers estimated ...

Alpha Centauri is a triple-star system, with one of its stars, Proxima Centauri, being the actual closest star to the Sun at 4.25 light-years away. Such star systems are not closed off ...

The Alpha Centauri system is made up of a pair of sun-like binary stars being circled by the red dwarf star Proxima Centauri, which is in turn orbited by at least one exoplanet. (Image credit ...

The Hubble Space Telescope captured a stunning view of the bright Alpha Centauri A (on the left) and Alpha Centauri B (on the right). ESA/NASA Our nearest stellar neighbor, Alpha Centauri ...

The Alpha Centauri star system is approaching the sun. Two researchers have determined how many objects from there have already reached us and could reach us. At the edge of the solar system ...

The solar system could be packed with 1 million alien visitors, space rocks shaken away from our cosmic neighbor Alpha ...
