　　China News Service, Beijing, March 6 (Zhou Yanling and Xu Xueying) Jiang Peng, deputy to the National People's Congress and chief engineer of the "China Sky Eye", said on the 6th that he is actively planning the FAST (500-meter Aperture Spherical Radio Telescope) core array project and is very confident that it will The low cost will maintain FAST's core competitiveness and leading scientific advantages in similar international equipment for a long time to come.

　　On the same day, the Guizhou delegation held an open group activity at the Second Session of the 14th National People's Congress.

　　"We discovered a pulsar in a binary system with an orbital period of only 53 minutes. The binary system is the pulsar with the shortest orbital period discovered so far. But the greatest significance of this discovery is not that it has the shortest orbital period, but This star is very rarely in a critical state of transition from the red-back spider system to the black widow spider system." Jiang Peng shared a wonderful discovery during the exploration of the universe by the "China Sky Eye" at the meeting.

　　"The whole world knows that butterflies hatch from cocoons, but how to prove it? The simplest and most direct way is to take a photo at the moment when it emerges from the cocoon and becomes a butterfly."
