Stephen Hawking has announced a major $100 million project known as Breakthrough Starshot— along side Russian billionaire Yuri Milner.
The two are teaming up on the hunt for alien life forms in outer space.
For the past few years, Hawking has warned of the dangers posed by intelligent extraterrestrials, saying that an advanced alien race could potentially wipe out humanity.
Astronomers believe an Earth-like planet could exist within the "habitable zones" of Alpha Centaur— the closest star system to Earth.
Breakthrough Starshot hopes to launch thousands of the tiny, light-propelled spacecraft—called "nanocrafts" -- with the goal of reaching the star system in twenty years.
The project makes it the biggest hunt for alien life ever staged.
