Is there life on other planets? What might aliens look like? Many people want to know the answers to these questions. Three of the richest people in the world hope to be the first to find extraterrestrial life. Mark Zuckerberg, the chief executive of Facebook, the Russian entrepreneur Yuri Milner and the astrophysicist Stephen Hawking contributed 100 million dollars to the search for extraterrestrial civilizations. They have stated that scientists are going to listen to signals from the planet called Earth 2.0, according to Mail Online.

Could there be life on this planet?

The planet called Terra 2.0 - officially called Proxima b -  is believed to hold favorable conditions for life.

This planet is located only four light years from Earth. The three billionaires have pledged to financially support an ambitious project named 'Breakthrough Listen' with 100 million dollars. This project is going to use the world's most powerful telescopes to capture messages from aliens.

Planet very similar to Earth

Two months ago, astronomers found clear evidence that the nearest Star, Proxima Centauri, is the sun of a planet which is very similar to Earth.

The project 'Breakthrough Starshot'

Milner stated exclusively for Mail Online that this news came just a few months after he and Stephen Hawking - with the support of Mark Zuckerberg -  started the project 'Breakthrough Starshot'. This project plans to launch a small spacecraft to Centauri, within a generation . The entrepreneur also said that they have a precise target now, and this makes the mission more tangible.

Proxima b accessible from Earth

Unlike other thousands of exoplanets discovered so far, Proxima b is accessible from Earth, according to scientists. Although four light years means a long way, the future generations of spacecrafts could achieve the trip to this planet in a few decades.

Could radio waves help researchers to find aliens?

Early next month, the team 'Breakthrough Listen' are going to search for radio waves that differ from the noise of the natural background. The Parkes Observatory from Australia is going to be used for this mission. This is the same observatory that was used to get live images from the Moon landing of Apollo 11 in 1969, according to the same source.
