What is the so-called Heavenly Eye?

It is my country’s single-aperture spherical radio telescope with independent intellectual property rights and used to explore the universe. With it, we can promote the understanding and detection of deep space in the universe and provide new possibilities for the development of astronomy.

How big is the "China Sky Eye"? It has a diameter of 500 meters and a launch area equivalent to 30 standard football fields. If you fill it with mineral water, each of the 7 billion people in the world can share 4 bottles on average. How far can it see? It can see through an area of ??more than 13 billion light years, close to the edge of the universe. Currently, the "China Sky Eye" is the world's largest and most sensitive single-aperture radio telescope. Drawing on the principle of parabolic antennas to listen to signals from the universe from the earth, the scientific name of the "China Sky Eye" is the 500-meter radio telescope. Unlike common optical telescopes that observe through visible light, radio telescopes "observe" the universe by receiving invisible radio waves in the universe. The thick atmosphere above us has two "windows": one is the visible light window, through which humans have observed the universe for thousands of years; the other is the radio window. In the 1930s, radio astronomy pioneer Karl Jansky The accidental discovery of a signal from the center of the Milky Way opened the curtain of radio astronomy, promoting mankind's understanding of the origin of the universe and the origin of life.
