美国航空航天局(NASA)的旅行者1号飞船发回的新数据表明,这艘飞船确实已经离开了日球层的怀抱,驶入了寒冷黑暗的星际空间。所谓的日球层,指的是包裹在太阳周围的一个由炽热的高能粒子构成的气泡。自1977年发射以来,旅行者1号一直在急速飞离太阳。最新测量数据显示,飞船周围等离子体的密度,已与理论预言的星际介质密度相符。根据这些数据,研究人员表示,旅行者1号大约
New data from NASA’s Voyager 1 spacecraft indicates that the spacecraft has indeed left the embrace of the Heliosphere into cold and cold interstellar space. The so-called sun-dome refers to a bubble of hot, energetic particles wrapped around the sun. Since its launch in 1977, traveler 1 has been rapidly flying off the sun. The latest measurements show that the density of the plasma around the spacecraft has been in line with the theoretical predicted density of the interstellar medium. Based on these data, researchers said that Travelers No. 1 is about
