A new paper published in The Astrophysical Journal has figured out what a habitable planet may look like in the Alpha Centauri star system, the closest start system to us at just 4.4 light-years.

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 ...

The Robinson family is one of many aboard a huge ship known as the Resolute, which is venturing to Alpha Centauri star system. It’s the closest to Earth, and the plan is to continue building a ...

Alpha Centauri, the nearest star system to the sun, is probably shedding comets and asteroids into our solar system — and even producing a few meteors in our sky. Located just 4.3 light-years ...

Scientists are starting to look for life in our galactic backyard. Alpha Centauri, two stars that at just over four light-years (about 25 trillion miles) away are the closest sunlike stars to our ...

Scientists have discovered that the sun and its nearest twin star, Alpha Centauri A, share an odd solar quirk: a puzzling cool layer in their wispy, hot atmospheres. The different temperatures of ...

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 ...

But could humans or spacecraft ever reach Alpha Centauri, the closest star system to our planet? Alpha Centauri is about 4.4 light-years (roughly 25 trillion miles, or 40 trillion kilometers ...

The Robinson family is one of many aboard a huge ship known as the Resolute, which is venturing to Alpha Centauri star system. It’s the closest to Earth, and the plan is to continue building a ...
