It is the first time Chinese scientists have discovered pulsars using the world's largest single-dish radio telescope, thus opening a new era of Chinese original space discovery, Yan Yun, director of the National Astronomical Observatories of China, said on Tuesday. The first two pulsars, named J1859-01 and J1931-01, were discovered in August and were confirmed in September by the 64-meter radio telescope at Parkes Observatory in Australia. J1859-01 is 16,000 light years from Earth and rotates once every 1.83 seconds, while J1931-01 is 4,100 light years away and rotates once every 0.59 seconds, according to scientists. Since its completion in September 2016, FAST has discovered two dozen highly possible candidates for pulsars, said Li Di, the telescope's deputy chief engineer. Last week, FAST also confirmed four new pulsars, but their details are still being analyzed. Pulsars are superdense cores of massive stars that went supernova and died, hence they have incredible mass, extremely strong magnetic fields, and they spin like a clock and shoot out strong beams of electromagnetic radiation, Li said. The conditions on a pulsar are far more extreme than any lab simulation on Earth. Examining them and seeing how they interact with other stars can help us tackle major scientific issues, such as the origin and evolution of the universe, finding gravitational waves and navigating spacecraft. Li said FAST is set to be fully operational by the end of 2019. In the meantime, scientists there will continue to test FAST and cooperate with foreign scientists on space exploration. event wristbandsmotivational wristbands for athletesballer bandswide rubber bands202mm to inchesjordan wristband rubber

In the message Xi pointed out that China and the ROK are important neighbors for each other. Bilateral relations have been comprehensively developed in the past 25 years since the establishment of diplomatic ties, with exchanges in all areas being enhanced, Xi said. The development of China-ROK relations has not only brought practical benefits for the people of both countries, but also made positive contributions to regional peace and stability, he said. Xi stressed that he has always attached great importance to the ROK and China-ROK relations. China would like to make joint efforts with the ROK to maintain the achievements of bilateral ties, he said. The two countries should strengthen political trust, properly handle disagreements, enhance coordination and cooperation under the basis of mutual trust and respect, to push forward the healthy and stable development of China-ROK relations, Xi said. Xi said he would like to make joint efforts with Moon to make the China-ROK relations better benefit the two countries and the people of both.

[Photo/Agencies] Moon Jae-in wins S Korean presidential election Liberal Moon Jae-in won the South Korean presidential by-election as he gained votes enough to confirm victory, vote count results showed Wednesday. With 91.3 percent of votes counted as of 3:07 a.m. local time (1807 GMT Tuesday), Moon garnered 40.5 percent, according to the national election commission. Hong Joon-pyo of the conservative Liberty Korea Party won 24.8 percent. Even if the remaining uncounted votes go to Hong, he will not defeat Moon. It confirmed Moon's victory with certainty. Ahn Cheol-soo of the centrist People's Party garnered 21.5 percent, trailed by Yoo Seong-min of the conservative Righteous Party with 6.7 percent. Sim Sang-jung of the minor liberal Justice Party had 6.0 percent support. Moon celebrated with jubilant supporters gathering at the Gwanghwamun square in central Seoul around midnight as his victory was assured by local media outlets in an early stage of vote count. In the televised speech, Moon told supporters that he will become a president for all the people from Wednesday, saying he will become a president of unity, caring about those who did not support him in the election. Before the speech, he told reporters at his party's building that he will achieve the two main goals of reform and unity people had wished for. Four other major candidates made concessions to Moon, even before less than 10 percent of votes were counted. The concessions led local media outlets to predict an assured election of Moon.
