Stephen Hawking will be making a big announcement today about space exploration. What will it be? Find out at noon, EST.

Hawking and Yuri Milner of the Breakthrough Prize have been building up to an announcement on Project Starshot. So far, the only thing known about the new project is that it has to do with space exploration.

But what’s Hawking’s big reveal about the project? No one knows yet—but it’ll be streaming live right here at noon, EST. Watch along with us.

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.
