China announced plans to 'hunt' aliens with the largest telescope

China has announced the latest plan, searching for planets that live outside the Solar System by using the world's largest sound telescope to detect magnetic fields.

In the Journal of Astronomy and Astrophysics, the team of China's 500-meter aperture Spherical Sound Telescope Project (FAST) announced their ambitious plans for the next decade. , including the mission of hunting for planets with life.

FAST is a telescope up to 500 meters in diameter, located in the Dawodang limestone basin in Guizhou Province. This project has been put into operation since September 2016.

One of FAST's main scientific missions is to 'listen' to hidden stars and interstellar audio signals, including any signals coming from other ' Earths' in the universe. 'In theory, if there is a cosmic civilization, the sound signal it emits will be similar to the signal we receive when a hidden crystal (neutron star) approaches us , ' said Qian Lei. , from the Chinese Academy of Sciences spoke on China Central Television (CCTV).

Scientists have long been trying to find planets that may have life, but they focus on the planet's composition, the distance from its star (to judge whether water can exist). and see if the planet has an atmosphere. These are essential requirements for life on Earth to exist, so it may also be true for other planets.

However, in the latest issue, Chinese and French researchers working at FAST say they are planning to search for extraterrestrial planets about 100 light-years away from Earth by looking at the word school

Our Earth's magnetic field protects the planet from the Sun's wind - which is the flow of charged particles released from the Sun, which will clean up the Earth's atmosphere without a shielded magnetic field.

The team believes that, because the Earth's magnetic field provides a protective sleeve on the planet, it would be reasonable to assume that this may be true for other worlds deep in the universe.

'If the Earth stops spinning, the magnetic field will disappear. Without the protection of the magnetic field, Earth gas will be swept away by the solar wind. Therefore, humans and most lives will not be able to survive in the face of the harsh environmental conditions of the universe , 'Xinhua quoted FAST chief scientist Li Di as saying.

According to Mr. Li, his team can study the magnetic field surrounding planetary planets by searching for the interaction between the solar wind (or the stellar wind) and the magnetosphere - a process that will release sound radiation. .'All planets with magnetic fields in our solar system have been discovered to release sound radiation, which can be measured and studied by sound telescopes. But studying the planet's magnetic fields is not possible with infrared and optical astronomical observation devices. Does foreign planets have magnetic fields? If so, they would probably emit sound radiation under the influence of their mother's stars (like the solar wind), " said Li Di.

If it is possible to confirm the existence of a magnetic field using FAST, his team will be able to study it to determine if life exists on the planet, Li said.
