Scientists have found that the number of ancient quasars has doubled ajviewer

The scientists found that the number of ancient quasars increased the most deadly thing in the universe as a quasar quasar is one of the brightest objects, this is not only because of their high brightness, but also because of their heavy fog light of the early universe, let us through them to understand what happened then. Tencent space news, according to foreign media reports, quasars are large galaxies in the center of the supermassive black hole accretion of material composition of the structure, due to the observation of similar stars named after. Quasars are very bright, so they are often used as beacons for astronomical observations. They are also the most distant objects that we can study so far. Carnegie Mellon University Eduardo Bañ ADOS led the research team of the latest observations found 63 quasars. According to the observations, these quasars have been born only 1 billion years after the birth of the universe (that is, the current actual age is about 14 billion years). Never before have so many researchers found that distant quasars in the thesis, a sample of 63 is almost the number of quasars known as on the research papers will be published in the Astrophysical Journal "· series" on the supplement. Quasars are one of the brightest objects, not only because of their high brightness, but also because they illuminate the dense early universe, so that we can understand what happened at that time. But until now, we know that the number of quasars is still very small. It also limits the mysteries of the universe in which scientists explore the early universe. One of the difficulties is that they find the quasar itself in the universe is extremely rare, although scientists have been searching for quasars on efforts for decades, but it is still look for a needle in the ocean. Bañ the ADOS team’s discovery of quasars will provide valuable information for the 1 billion years after the big bang. This period of time is the focus of astronomers. As we all know, the universe was born in the big bang, the big bang threw hot material into every corner of the space. But the whole universe was dark for a long time. Until the material cools down, protons and electrons are formed, and protons and electrons combine to form hydrogen atoms. The gravitational pull of these hydrogen atoms together and compress them to trigger the fusion of the nuclei. The fusion reaction gives off light at the same time as the formation of a heavier nucleus, allowing the universe to shine again. We now believe that there should be quasars in the first light of the universe. In this phase of the light, the scientists still have a lot of questions. More samples of ancient quasars will help them figure out what happened in the 1 billion years after the big bang. Bañ ADOS said that the formation and evolution of the earliest light sources in the universe and their structure are one of the greatest mysteries of astronomy. The best tool for us to find the answer is a very bright quasar, including the 63 newly discovered. Until recently, the results of the study were still limited by the very small number of samples of ancient quasars. Thanks to this discovery, it can be seen in recent years相关的主题文章:
