On April 17th, the reporter learned from the FAST Operations and Development Center of the National Astronomical Observatory that the 500 meter Aperture Spherical Radio Telescope (FAST), known as the "Chinese Eye", has discovered more than 900 new pulsars. Produce a series of world-class achievements in the fields of rapid radio burst origin and gravitational wave detection; The core components of independently developed receivers are expected to go abroad; The construction of the FAST core array is ready to take off... With a starry sky, we are constantly moving forward. The Chinese Heavenly Eye is continuously providing Chinese wisdom to the world's astronomy and Chinese technology to the global engineering community. The frequent achievements of the "Chinese Heavenly Eye" are well-known national treasures. In order to achieve early results, produce more results, produce good results, and achieve great results, Chinese scientists constantly challenge their cognitive and technological limits, using "Chinese creation" to polish the profound "heavenly eye". As of now, the Chinese Sky Eye has discovered over 900 new pulsars, including at least 170 millisecond pulsars, more than 120 binary pulsars, and 80 faint occasional pulsars. "We are expanding the limits of human understanding of the universe," said Han Jinlin, the head of the National Astronomical Observatory's galactic pulsar survey project. In the 50 years from the discovery of the first pulsar by humans to the discovery of the first pulsar by FAST, less than 3000 pulsars have been discovered worldwide. On October 10, 2017, China's Tianyan announced the discovery of six new pulsars, achieving a breakthrough of zero. This is the first time China has discovered pulsars using its independently developed radio telescope. At present, more than 900 new pulsars have been discovered by the Chinese Celestial Eye, which is more than three times the total number of pulsars discovered by other telescopes at the same time internationally. Among them, 80 faint occasional pulsars were discovered, and compared to normal pulsars, their radiation flux density was one order of magnitude lower, with the lowest reaching the sub micro center level. In Han Jinlin's view, the study of these occasional pulsars is of great significance for understanding how many dense neutron star remnants form after star death in the Milky Way and revealing unknown physical processes of pulse radiation. Han Jinlin told reporters that if we compare searching for pulsars to picking fruits, previously discovered pulsars are relatively close to the ground and easy to pick, while the more than 900 new pulsars discovered by the Chinese Eye are farther or more difficult to pick. Because each pulsar has its own unique pulse and stable rotational frequency, they are like "lighthouses" with unique signal markers in the universe. If humans can achieve interstellar travel in the future, these pulsars will provide navigation for human travel in the vast universe. "We accurately measure the coordinates of pulsars in space and constantly monitor the phase and corresponding positional relationships of multiple pulsar signals during the journey, so that humans will not get lost during interstellar travel," said Han Jinlin. In recent years, the "Chinese Eye" has made significant contributions to exploring the mysteries of the universe by observing the pulse of a black hole in the radio band for the first time, detecting key evidence of the existence of nanohertz gravitational waves, and detecting and constructing the world's largest neutral hydrogen galaxy sample. In the face of the unknown and the future, humanity shares a common destiny. From the moment of its birth, the "Chinese Eye" has shouldered its mission.
