有史以来最具历史意义的天空景观之一发生在1054年7月，当时蟹状超新星在黎明的天空中闪耀。中国宫廷占星家在1054年7月4日早上第一次在天官星（现在被归类为Zeta Tauri）旁边看到了这颗客星。这颗超新星在1054年7月下旬达到峰值，比金星略亮，在白天可以看到23天。这颗星如此明亮，以至于世界各地的每个文化都不可避免地独立发现了这颗超新星，尽管只有9份报告幸存下来，包括中国、日本和君士坦丁堡。这张iPhone照片摄于2025年7月26日早上图森附近的信号山，忠实地再现了1054年的螃蟹黎明，展示了霍霍坎人看到的天空。金星，作为超新星的替身，离现在的蟹状星云超新星遗迹的位置很近。夏日的黎明，在明亮的金星照耀下走到户外，问问自己：“在古代，当你突然看到螃蟹的黎明时，你会怎么想？”

One of the all-time historic skyscapes occured in July 1054, when the Crab Supernova blazed into the dawn sky. Chinese court astrologers first saw the Guest Star on the morning of 4 July 1054 next to the star Tianguan (now cataloged as Zeta Tauri). The supernova peaked in late July 1054 a bit brighter than Venus, and was visible in the daytime for 23 days. The Guest Star was so bright that every culture around the world inevitably discovered the supernova independently, although only nine reports survive, including those from China, Japan, and Constantinople. This iPhone picture is from Signal Hill near Tucson on the morning of 26 July 2025, faithfully re-creates the year 1054 Dawn of the Crab, showing the sky as seen by Hohokam peoples. The planet Venus, as a stand-in for the supernova, is close to the position of what is now the Crab Nebula supernova remnant. Step outside on a summer dawn with bright Venus, and ask yourself "What would you have thought in ancient times when suddenly seeing the Dawn of the Crab?"
