A Russian billionaire wants to send a spaceship to a nearby planet that could have life


Back in April, Russian billionaire Yuri Milner promised $100 million toward an unusual and ambitious plan to discover a new star system that might harbor life.

The mission known as 'Breakthrough Starshot,' plans to accomplish this by sending an incredibly small set of spaceships across the galaxy at 20 percent the speed of light pushed forward by immensely powerful lasers.

This is how the probes will be dispersed in space. 

Milner teamed up with renowned physicist Stephen Hawking to make this dream come true. Initially the pair were planning their destination to be Alpha Centauri, the second-closest star system to planet Earth -- it's located 4.37 light-years or 25.7 trillion miles away.

But a recent groundbreaking discovery of a closer planet could shift Starshot's plans in a new direction. Astronomers announced this week they'd discovered a new planet called 'Proxima Centauri' that's potentially habitable and closer by about 1 trillion miles than Alpha Centauri.
