The spacecraft have also provided data on the heliosphere, a kind of protective bubble around our solar system.

宇宙飞船还提供了关于日球层数据，日球层是太阳系周种保护气泡。

It appears that the spacecraft left the sun's heliosphere more than a year ago.

旅行者1号离开日球层已经年多了。

In 2012, forty years after its departure from Earth, Voyager 1 surpassed the heliosphere and entered interstellar territory.

2012 年，在离开地球 40 年后，航海者号飞越了日光层，进入了星际领土。

On its way to the edge of the heliosphere, Voyager 1 photographed the surfaces of our gas giants.

在前往日球层边缘途中，航海者号拍摄了我们气态巨行星表面。

In the last 50 years, we have explored and studied the outer boundary of our solar system, breaking through the heliosphere into interstellar space.

在过去 50 年里，我们探索和研究了太阳系外边界，突破了日球层进入星际空间。

The heliosphere is a " bubble" around our solar system at the edge of the sun's magnetic field, which commonly defines the boundary between stellar and interstellar space.

日球层是太阳磁场边缘绕我们太阳系个“气泡”，它通常定义了恒星和星际空间之间边界。

Its research supplied NASA with a critical glimpse into the formation of young solar systems.By 2043, New Horizons may enter interstellar space, where it will conduct a detailed study of space outside the heliosphere.

它研究为美国宇航局提供了对年轻太阳系形成重要瞥。到 2043 年，新视野号可能会进入星际空间，在那里它将对日光层外空间进行详细研究。
