This fact filled article about the impressive plan to explore Alpha Centauri that’s been hitting all the major news outlets is pretty darned intriguing. It involves tiny probes about the size of iPhones that could travel to our nearest space neighbor, look around, and send home information. It would take a long time, of course, but advances in miniaturization in particular make what seemed impossible not so long ago into a technically feasible ambition. The fact that Stephen Hawking is involved makes the whole prospect even more exciting. It’s the stuff of dreams, and science fiction, and a scientific reality we’re all privileged to witness unfolding its wings. Quite literally.
