1·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。

2·Many astronomers think that the limit of the heliosphere, known as the heliopause, is about 9 billion miles (15 billion kilometers) from the sun.

许多天文学家认为，日球层的边界是太阳风顶层，距离太阳90亿英里(150亿公里)。

3·Still operational, both Voyagers are headed towards the outer boundary of the solar system, in search of the heliopause and the beginning of interstellar space.

目前二艘航行家太空船仍然持续运转，并努力地往太阳系的边界移动，探寻太阳风层的顶部和星际空间的起点。

4·It's now 17 billion kilometers from Earth. And it should be close to the heliopause, where the plasma flowing outward from the sun no longer holds back the interstellar winds.

发射于1977年的航海家一号如今距离地球已有170亿公里，现在应该已经接近太阳风顶层，在那里从太阳发射出的等离子太阳风已经不能抑制来自星际空间的宇宙射线。

5·In 1999, the Light forces started constructing a Light barrier at the heliopause with the intention of containing darkness infection inside our Solar System and then later clearing it.
