heliopause

基本解释

The heliopause was expected to be a rather sharp boundary between the sun's domain and interstellar space.
太阳风顶层曾被认为是处在太阳系区域和星际宇宙之间一层电磁波动极其强烈的区域。
Or it could mean that Voyager 1 has already crossed the heliopause. Either way, the spacecraft becomes the first object in interstellar space created by intelligent life. That we know about.
无论哪种方式，在我们的认知范围内，航海家1号已经成为了有史以来第一个由智慧生物创造的离开太阳系进入系外空间的地球物体。
Beyond the orbit of Neptune one finds the disk-shaped Kuiper belt, in which dwarf planet Pluto resides, and far beyond that is the giant, spherical Oort Cloud and the teardrop-shaped heliopause.
在海王星之外还有人发现了盘状的柯伊伯带，矮行星冥王星就位于这里。在更远的地方是巨大球状的奥尔特云（彗星仓库）和水滴状的太阳风顶层（太阳风在此遭遇星际物质）。

Eventually, after a decade or so, it should cross the heliopause and venture into interstellar space.
ECONOMIST: Rockets are not the only way to travel through outer space
In contrast, Voyager 1, the most distant spacecraft from earth, will not reach the heliopause until 2019—42 years after its launch.

But Dr Winglee estimates that as little as 40kg of gas would be enough to accelerate the craft on its way to the heliopause, where it would arrive about ten years after launch.

the boundary between the region of space dominated by the solar wind and the interstellar medium
