How do you send man-made probes to a nearby star? According to NASA-funded research at the University of California, Santa Barbara (UCSB), the answer is simple: assemble a laser array the size of Manhattan in low Earth orbit, and use it to push tiny probes to 26 percent the speed of light. Though the endeavour may raise a few eyebrows, it relies on well-established science – and recent technological breakthroughs have put it within our reach.
