哈勃揭示了福玛拉托附近两次稀有宇宙碰撞产生的尘埃碎片 揭开了一个长期存在的星球奥秘 Hubble reveals dusty debris from two rare cosmic collisions near Fomalhaut, debunking a long-held planet mystery.

美国航天局的哈勃太空望远镜在25光年之后的Fomallhaut恒星附近两次大规模宇宙碰撞中捕捉了稀有的尘埃碎片图像,从而解决了一个长达数十年的谜团。 NASA’s Hubble Space Telescope captured rare images of dusty debris from two massive cosmic collisions near the star Fomalhaut, 25 light years away, resolving a decades-old mystery. 一个曾经被认为是行星的亮点 被透露为短暂的尘埃 由空间岩石的碰撞产生 至少60公里宽。 A bright spot once thought to be a planet was revealed to be transient dust from collisions between space rocks at least 60 kilometers wide. 这些事件发生在20年之内,极为罕见——可能每10万年在这类地区发生一次——使这种双重事件令人吃惊。 The events, occurring within 20 years, are extremely rare—possibly once every 100,000 years in such regions—making this double occurrence surprising. 碎片暂时模仿行星,但现在正在散落。 The debris temporarily mimicked planets but is now dispersing. 科学家说,研究结果提供了对行星形成的一种实时观察,与太阳系的“小行星图片”相提并论。 Scientists say the findings offer a real-time look at planetary formation, likened to a “toddler picture” of our solar system. 该研究报告发表在《科学》上,其中突出了这些暴力事件如何影响行星系统,并强调哈勃在发现动态宇宙过程方面持续发挥的作用。 The study, published in Science, highlights how such violent events shape planetary systems and underscores Hubble’s ongoing role in uncovering dynamic cosmic processes.
