Let’s explore this cosmic perspective together. How big is the universe? It’s a question that stirs both wonder and humility.

In the vastness of the universe, distances between celestial bodies are mind-boggling, with even light taking thousands of ...

Alpha Centauri is host to two sun-like stars, and a third star – the red dwarf Proxima Centauri, which is already believed to have one planet in a Goldilocks orbit, discovered in 2016.

Alpha Centauri is also the very closest system in the galaxy, lying just 4.37 light—years away and providing a uniquely intimate perspective on any possible planets there.

Scientists René Heller and John Armstrong contend that there might be a planet even more suitable for life than Earth 4.3 light years away orbiting the star Alpha Centauri B.

So, while humans will probably never reach Alpha Centauri, it's possible that spacecraft designed to go a much smaller fraction of the speed of light could reach these stars in a human lifetime.

If the nearest star system, Alpha Centauri, does harbor rocky planets similar to Earth as new findings suggest, there exist a host of ways to get us there, in theory.

Our sun's closest star system, Alpha Centauri, is "almost certainly" home to small Earth-like planets capable of harbouring alien life, scientists have claimed. Alpha Centauri, which is "only" 24. ...

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, 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 ...
