哈勃揭示了在Fomalhaut附近两起罕见的宇宙碰撞事件,
Hubble reveals two rare cosmic collisions near Fomalhaut, explaining a long-missing "planet" as dust from giant space rocks.
美国航天局的哈勃空间望远镜从25光年之后的年轻恒星福玛哈托附近两次大规模宇宙碰撞中 捕捉到了罕见的尘埃碎片图像
NASA's Hubble Space Telescope has captured rare images of dusty debris from two massive cosmic collisions near the young star Fomalhaut, 25 light years away.
曾经被认为是一个行星的亮点 被透露为短暂的尘埃 来自空间岩石之间至少60公里宽的撞击
The bright spot once thought to be a planet was revealed to be transient dust from impacts between space rocks at least 60 kilometers wide.
这些碰撞发生在20年期间,极为罕见——可能每10万年发生一次——使双重事件令人吃惊。
These collisions, occurring within a 20-year span, are extremely rare—possibly once every 100,000 years—making the dual events surprising.
碎片云在散落之前暂时模仿行星, 给行星的形成提供了实时的一瞥。
The debris clouds mimicked planets temporarily before dispersing, offering a real-time glimpse into planetary formation.
科学家计划监测尘埃以研究其演变过程,研究结果发表在《科学》上。
Scientists plan to monitor the dust to study its evolution, with findings published in Science.
