After nearly two years of national acceptance and nearly one year of opening to the outside world, about 500 pulsars have been discovered, and a series of important scientific achievements have been made in important astronomical fields such as neutral hydrogen spectrum measurement in interstellar magnetic field, rapid radio burst observation and research.
The "500-meter spherical radio telescope (FAST)" was officially opened to the world, collecting applications for observation from astronomers around the world, and demonstrating the cooperation concept between China scientists and the international scientific community. A total of 72 observation applications from different countries were received in the solicitation activity * * * 6 hours. Finally, 27 international observation applications from 14 countries (excluding China) were approved, and scientific observation began in August 20021year.
However, with the continuous development of human civilization, people's understanding of the earth and the universe is also increasing, and the invention of astronomical telescopes is indispensable for human beings to truly understand the universe. It can be said that since human beings invented the astronomical telescope, a brand-new door of the universe has been opened to human beings. For the first time, human beings know through the astronomical telescope that the moon is actually barren.
Based on the international leading edge of the sensitivity of the 500-meter spherical radio telescope (FAST), the combination of the 500-meter spherical radio telescope (FAST) and Fermi-LAT, an important space astronomical facility in high energy band, may make a major scientific breakthrough.
The universe is vast and no one knows how big it is. Since human beings were born on the earth millions of years ago, they have evolved step by step and finally formed human civilization. In ancient times, people's understanding of the universe was blank. Many people think that the earth is the whole world, and the sun, moon and stars in the sky all belong to the earth and revolve around it.
The sensitivity of the celestial eye is very high. For example, if you make a phone call on the moon, the sky eye can detect it, which other astronomical telescopes can't do. Up to now, 59 high-quality pulsars have been discovered by the 500-meter spherical radio telescope (FAST), of which 44 have been confirmed as newly discovered pulsars.
