Animation about solar sailing to the nearest star

In this wonderful animation, billionaire Russian physicist and investor Yuri Milner explains his effort to launch tiny probes, powered by 12 foot solar sails, on an interstellar mission to the nearest star, Alpha Centauri, within two decades. Cosmologist Stephen Hawking and Facebook founder Mark Zuckerberg are on the board of Milner's group, called Breakthrough Initiatives. The project builds on decades of work by scientists Carl Sagan, Louis Friedman, and Bruce Murray who pioneered solar sail technology through the Planetary Society, the fantastic citizen-funded space advocacy and research organization they co-founded in 1980. Indeed, Friedman is an advisor to Milner's Starshot effort.
