The triple star system of Alpha Centauri is only 4.3 light-years—about 25 trillion miles—away. The possibility of an earth-like world orbiting our nearest neighbor has been a kind of holy grail of astronomy — and something taken for granted by countless SciFi authors.
Yesterday, the European Southern Observatory announced they'd confirmed the existence of a planet in Alpha Centauri, the star system nearest to Earth. For many of us, it was like a dream come true. In the annals of science fiction, Alpha Centauri is like the Mars of star systems. Because it's the closest system to…
This is huge. We've discovered a lot of exoplanets, including rocky Earth-like ones, in far-away star systems. But the European Southern Observatory (ESO) announced this afternoon that our solar system's nearest neighbor, a brilliant trinary star system called Alpha Centauri, has a planet that's roughly the mass of…
Located just 4.3 light-years away, the Alpha Centauri star system is our closest neighbor. But theirs is a very different solar system, as it's home with not one, not two, but three stars. Here's the short guide to Alpha Centauri.
The Sun's tremendous gravitational pull actually warps the fabric of space around it, creating focal points where light comes together. We could use these focal points to build the most powerful telescopes ever and communicate with spaceships in Alpha Centauri.
If you take humanity's current energy and technological capacity and project a steady increase into the future, the chances of us reaching the stars any time soon look bleak. Even our nearest stellar neighbor is at least 300 years away.
