Chinese Astronomers Observe Supernova SN 1054

On July 4, 1054 CE, Chinese astronomers recorded a bright 'guest star' in the constellation Taurus near Zeta Tauri. This supernova, designated SN 1054, remained visible in daylight for 23 days and appeared in the night sky for nearly two years. Chinese imperial astronomical logs documented its location and brightness, noting it was approximately four times brighter than Venus. Japanese, Arab, and possibly Native American astronomers also observed this event. The explosion created the Crab Nebula and its pulsar remnant.
