FAST has discovered more than 300 pulsars. Will aliens be discovered?

After more than 20 years, this idea has become a reality. Known as "Tianan in China", the 500-meter spherical radio telescope was built and opened in Guizhou. This is the independent intellectual property right of China, the largest short-caliber and most sensitive radio telescope in the world. The 500-meter spherical radio telescope 3354 "Tianan, China" is located in the natural karst depression around Dagula Mountain in Pingtang County, Nanzhu, Guizhou Province. Its total area is equivalent to 30 standard football fields. If filled with water, everyone in the world can distribute 4 bottles of water. China scientist Nan, who put forward bold ideas, is in charge of the research and preliminary design of "Tianan in China". It is not easy to choose construction land. This matter alone has been practiced for 12 years, and finally 39 1 condition was selected to replace the lowest and most suitable condition, namely the big oyster in Pingtang County, Nanzhu, Guizhou.

Do you want to punch in? First of all, we should arrive at the Tianan Science Base in China, located in Tianwen Village, Ganglong, Pingtang County, Qiannan Yi and Miao Autonomous Prefecture. Make an appointment online according to regulations, store electronic equipment, and of course, put down your mobile phone, go through security check and take a bus to the ground floor of the observatory. Climb the fitness center and the 789 stairs, relax, transfer to the vehicle to climb the mountain, and then come to the Tianan 3354 Observatory in China, where you can see the spectacular scenery of the Eye of the Sky. In order to ensure the electromagnetic environment for scientific observation in the whole life cycle of China Tianan, with the support of relevant state departments and Guizhou Province, Pingtang County has successively relocated villages in the core area and closed all communication base stations in and near the core area. Therefore, after entering the area, all kinds of electronic devices of tourists will be in a state of no signal.

Mars may be the planet most similar to the Earth, with atmospheric and seasonal changes, but its air is thin, accounting for only 1% of the earth's sea level air. Because the atmosphere of Mars is too thin, asteroids often hit the surface of Mars, and there are sand and stones everywhere, devouring the planets blown by sandstorms under the storm. But this does not mean that there is no life on Mars. A few decades ago, humans thought that the existence of the earth was unique. It is the only planet we know that life was born and evolved into millions of species. Because of the abundant sunshine, warm seawater and the protection of the earth's atmosphere, we certainly think that these are indispensable conditions for life, which excludes the possibility of life on other known planets in the solar system.

Later, biologists began to explore the darkest and coldest places on earth, and even found active creatures, which biologists called extreme parasites. I like extreme creatures that don't need light and oxygen but are full of vitality, while people who like extreme creatures live under great atmospheric pressure. Some scientists assert that there will be no life on the frozen wasteland of Antarctic ice. An explorer photographed a rock 2 meters below the ice and found a group of microorganisms in the rock.
