科学家发现新的超新星类型 SN2021yfj, 揭示了对恒星进化的稀有洞察力。 Scientists find new supernova type, SN2021yfj, revealing rare insights into star evolution.

天文学家发现了一种新型超新星,叫做SN2021yfj或1型,为恒星的内部层提供了罕见的视角。 Astronomers have discovered a new supernova type, named SN2021yfj or Type 1en, offering a rare view into a star's inner layers. 这颗超新星显示恒星在爆炸前 已经失去了外层 揭示了硅等更重元素 Found 2 billion light-years away, this supernova shows the star had lost its outer layers, revealing heavier elements like silicon before exploding. 这一发现对目前的星系进化理论提出了挑战,并表明巨型恒星在爆炸前可能会失去重要物质,这种现象可能很少见,但对了解星体进化很重要。 This discovery challenges current theories of stellar evolution and suggests that massive stars might lose significant material before exploding, a phenomenon that could be rare but important for understanding star evolution. 未来望远镜可能有助于发现更多此类事件。 Future telescopes may help find more such events.
