The other, Proxima b, is closer in—so close that its year lasts only 11 days. ... Let’s say an advanced civilization on one star wants to reach the inhabitants of another star many light-years ...

Greetings, Citizens of Earth! You’ve probably heard about the story, published in The Guardian, a respectable newspaper in the UK, about the potential discovery of an alien signal from the Proxima ...

In 2016, researchers spotted Proxima b, an apparently Earth-size world orbiting the star in what seems to be the habitable zone, the region where liquid water could exist on the surface. The star ...

Breakthrough Starshot, the Stephen Hawking and Mark Zuckerberg-backed plan to send spacecraft to our stellar neighbors, has a new target, and it wants you to have the chance to glimpse it up close.
