螃蟹的黎明
Dawn of the Crab

1054 年 7 月，蟹超新星在黎明的天空中綻放出耀眼的光芒，這是史上最具有歷史意義的天象之一。中國宮廷占星家於 1054 年 7 月 4 日早晨在天官星（現被編入金牛座 Zeta 星）旁邊首次看到了這顆客星。這顆超新星在 1054 年 7 月下旬達到頂峰，亮度略高於金星，在白天可見 23 天。客星如此明亮，以至於世界上所有文化都不可避免地獨立發現了這顆超新星，儘管只有九份報告存世，其中包括來自中國、日本和君士坦丁堡的報告。這張 iPhone 照片是 2025 年 7 月 26 日早晨從圖森附近的訊號山拍攝的，忠實地再現了 1054 年的巨蟹黎明，展示了霍霍卡姆人看到的天空。金星作為超新星的替身，靠近現在蟹狀星雲超新星遺蹟的位置。在夏日的黎明走出戶外，伴著明亮的金星，問問自己："在古代，突然看到蟹狀星雲的黎明，你會怎麼想？"
原文：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?"
