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

旅行者1号离层已经一年多了。

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

2012 年，在离地 40 年后，航海者一号飞越了光层，进入了际领土。

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

在前往层边缘途中，航海者一号拍摄了我们气态巨行。

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，突破了层进入际空间。

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.

层是太阳磁场边缘围绕我们太阳系一个“气泡”，它通常定义了恒和际空间之间边界。

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一瞥。到 2043 年，新视野号可能会进入际空间，在那里它将对光层外空间进行详细研究。
