On February 1, 2003, Eastern Time in the United States, during the 16-day space journey back to Earth, the Space Shuttle Columbia suddenly disintegrated, resulting in the tragic loss of all seven astronauts. Regarding the Columbia disaster, from top government officials to ordinary citizens, there was widespread mourning and sympathy for this unfortunate event. UN Secretary-General Kofi Annan stated that humanity's exploration of space knows no borders and that the Columbia disaster is a loss for all of humanity. A netizen posted online: "Exploring space is a common aspiration of all humanity, reflecting humanity's desire to uncover the unknown world. Let us pay the highest tribute to the heroes who sacrificed their lives for science!"
Throughout the long history of human progress, humanity has come to understand nature, conquer the universe, and achieve a leap from the realm of necessity to the realm of freedom. This is an endeavor filled with risks, and paying a price is inevitable. In fact, throughout the arduous journey of space exploration, setbacks, failures, and sacrifices have never ceased. Today, humanity's understanding of space is possible because of the dedication of countless scientists and astronauts who are selfless, fearless, relentless, and unwavering. They have led Earth step by step to open the mysterious door of the unknown universe, expanding the boundaries of Earth's technology and extending the reach of human vision into the depths of the cosmos. Humanity's exploration of the universe will continue. The driving force behind space exploration comes from an insatiable thirst for knowledge. Space exploration can broaden our horizons. So, what depth has humanity's understanding of the universe reached today? This is the main content this book introduces. One thread of the book begins with "the universe's birth from nothingness," combining the latest achievements in scientists' exploration of the universe to provide a detailed introduction to the various developments and changes during the universe's infancy, adulthood, and old age, making it a kind of encyclopedia about the universe. The other thread of the book progresses from far to near, first introducing the latest research findings on the universe, then exploring humanity's latest discoveries about the Milky Way, the solar system, and Earth. This helps readers realize that the blue planet we inhabit is merely a faint, insignificant star in the vast universe, and the sphere where 6 billion people live is like a tiny, drifting boat in the Milky Way.
