摘　　要：China’s Einstein Probe(EP)astronomical satellite has,for the first time in human history,detected soft X-ray signals from an explosion in the early universe,opening a new window for research into the young cosmos.The findings were published in the journal Nature Astronomy on January 23,2025.The Wide-field X-ray Telescope onboard the EP satellite observed a faint pulse signal from a burst event in the soft X-ray band on March 15,2024.This burst,designated as EP240315a,exhibited rapid brightness fluctuations and persisted for over 17 minutes before gradually fading away.Subsequent observations by telescopes from other countries confirmed that this burst originated from the distant early universe.
