How to evaluate the live broadcast of the Chinese Academy of Sciences' 2022 New Year speech? Academician Wu Xiangping said that Tian Yan had searched for the signal of suspected alien civilization.

The vast space will always arouse people's infinite desire to explore, among which the most concerned is the topic of whether aliens exist.

Recently, in the live broadcast of the 2022 New Year speech of the Chinese Academy of Sciences, Wu Xiangping, an academician of the Chinese Academy of Sciences and an astrophysicist, said that he believed in the existence of aliens.

According to Academician Wu, since 1959, people have been looking for special telescopes to collect signals from space, hoping to find aliens. At the earliest, the target was replaced by a radio receiver. On August 1977, it received a signal that was said to be from an alien, which has not been deciphered so far.

Two months ago, Australian astronomers used a telescope with a diameter of 64 meters to receive a signal in proxima centauri, 4.2 light years away. Later, it was confirmed that the signal was not man-made interference, and the frequency was 982 MHz, which was similar to that of a mobile phone, so it was confirmed that it was the first alien call received by human beings.

Academician Wu also said that he hoped that astronomers would one day find a second earth suitable for human habitation and send everyone there by travel. At the same time, he also expressed his hope to truly establish contact with aliens.

In this regard, some netizens agreed, "The Milky Way has more than hundreds of billions of star systems similar to the solar system, and there are at least hundreds of billions of galaxies similar to the Milky Way in our universe. There are many kinds of life on earth, and life in the universe is endless. "
