Back on Earth, about a thousand years ago, the early human civilization once looked up at the sky. In 1054, Chinese science described the emergence of a bright new star. It may be fresher than others and can be seen in mature life. But it is amazing. The position of the Crab Nebula in the sky, they saw the moment when the Crab Nebula was born. The same place where the Chinese saw the star. (Finally, I want to recall, my idol Nicholas. Sla.)
