Since the "China Sky Eye" (FAST) was officially opened for operation through national acceptance on January 11, 2020, based on the obvious advantages of ultra-high sensitivity, it has become a sharp tool for viewing the sky in the field of medium and low frequency radio astronomy.
Where did the universe come from and where is it going? Can FAST see the edge of the universe? On the occasion of the two years since FAST passed the national acceptance, let us explore fast's cosmic vision together.
FAST is a new generation of large radio telescopes independently designed and built by Chinese scientists represented by Nan Rendong in order to trace back to the original universe. As the world's largest and most sensitive single-aperture radio telescope, it has greatly increased the scope of space in the universe that humans have effectively explored.
Located 71,800 light-years from the center of the Milky Way, FAST found a neutral hydrogen structure up to 16,300 light-years long. Chinese astronomers have named it "Cattail," which could be the farthest and longest-scale giant fiber structure in the Milky Way today, or a new section of the spiral arm.
In the future, FAST will produce scientific achievements to deepen human understanding of the universe in the directions of the origin and physical mechanism of fast radio bursts, the study of neutral hydrogen universe, pulsar search and physical research, pulsar timing and low-frequency gravitational wave detection.
Eyes like torches, picking stars away from the light years. Take the lead at a glance and drive high-tech innovation. Fire eyes golden eyes, exploring the unknown. Where can fast, with deep eyesight, take the human eye?
