Visionaries XXI century will seek aliens, including scientist Stephen Hawking, the director of the social network Facebook, Mark Zuckerberg, and Russian billionaire Yuri Milner embarked on a project to launch toward the star system Alpha Centauri thousands of spaceships postage stamp size.
Alpha Centauri is a star located trillion kilometers away from Earth, and could be achieved in “just” Twenty years through a project called Starshot, according to international media.

The search for extraterrestrial life in other galaxies anticipated that thousands of miniaturized spacecraft are directed to the Alpha Centauri star system at a speed of 161 million kilometers per hour.
The vehicles will be equipped with a species of ‘solar sails’ and will be powered by laser beams. Preliminary calculations estimate that if these ships fail to reach a celestial body in the Alpha Centauri system and fail to capture photos, the image would take 4 years to return to Earth.
The British astrophysicist Stephen Hawking, author of this project, has defended the need to search for extraterrestrial intelligence.
Meanwhile, Yuri Milner believes that this project is of great importance for all mankind and says we now have technology and capabilities, software and hardware, to try to find the answer to a fundamental question:
“are we alone in the universe? I think that over the next ten years will be able to achieve significant, more important than that achieved in the last 55 years progress, “said Milner.
he said that” no government is involved in the project. It is an international and global initiative. The telescopes are located worldwide. We will not hide information or results, but will give access to raw data for others, both scientists and amateurs or anyone who wishes to participate, they can search themselves. So everyone can be lucky enough to find something in the signals and data to offer citizens “

Meanwhile the project’s executive director and former director of the Ames Research Center of NASA, Pete Worden said that “we want to launch a challenge to scientists and engineers around the world to do something really shocking.”
Worden also reported that from the point of view of physics, no obstacles. However, the work is an important challenge for engineering. The most important among them is the distance.
Alpha Centauri is four light years from Earth, meaning it would take about 30,000 years to get there using a faster spacecraft available today. “
