Features: Facing the mysterious universe, how many people have devoted their entire lives to it, and sometimes even a lifetime seems too short. It's best to span several lifetimes. Here, the author introduces a long astronomical story, the protagonist of which has experienced nearly a thousand years of history. Over these long years, dozens of generations of astronomers have dedicated their efforts to it. The Crab Nebula is one of the most striking celestial bodies in modern literature. When you open a regular astronomy book, you often see a beautiful photo of the Crab Nebula in front of you. Some content of this book was published by the author in a book titled "The Crab Nebula" in 1981. Time flies, and more than 20 years have passed. In this rapidly developing 20 years, there is one thing that remains unchanged—the brilliance of the Crab Nebula itself. Not only has it remained unchanged, but it has also become more dazzling. The encouraging news is that the research on the main subject of this book—the pulsar—has once again won the Nobel Prize. The study of a single celestial body winning the Nobel Prize twice is probably unprecedented. All these advancements have prompted the author to feel that this book must be rewritten.
