科学家观察到了银河系外的神秘而持久的伽马射线爆炸。 Scientists have observed a mysterious and long-lasting gamma-ray explosion outside our galaxy. 与仅持续几分钟或毫秒的典型伽马射线暴不同,这次7月首次见到的事件持续了整整一天。 Unlike typical gamma-ray bursts, which last only minutes or milliseconds, this event, first seen in July, persisted for an entire day. 欧洲领导的小组于8月公布了其调查结果,指出需要更多观察才能了解和找到这一不寻常宇宙事件的来源。 The European-led team published their findings in August, noting that more observations are required to understand and locate the source of this unusual cosmic event.
