A Concentrated Beam of Particles and Photons Could Push Us to Proxima Centauri

Getting to Proxima Centauri b will take a lot of new technologies, but there are increasingly exciting reasons to do so. Both public and private efforts have started seriously looking at ways to make it happen, but so far, there has been one significant roadblock to the journey—propulsion.

To solve that problem, Christopher Limbach, now a professor at the University of Michigan, is working on a novel type of beamed propulsion that utilizes both a and a laser to overcome that technology's biggest weakness.

Lunar swirls are light-colored, sinuous features on the Moon's surface, bright enough to be visible from a backyard telescope. Some people think they look like the brushstrokes in an abstract painting. But these are not mere artistic flourishes: NASA images show that the tendrils from some lunar swirls extend for hundreds of miles. Lunar swirls have defied easy explanation, but recent mode
