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

旅行者1号离开球层已经一年多。

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，航海者一号飞越层，进入际领土。

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

在前往球层边缘的途中，航海者一号拍摄我们气态巨行的表面。

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

在过去的 50 年里，我们探索和研究太阳系的外边界，突破球层进入际空间。

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.

球层是太阳磁场边缘围绕我们太阳系的一个“气泡”，它通常定义恒和际空间之间的边界。

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.

它的研究为美国宇航局提供对年轻太阳系形成的重要一瞥。到 2043 年，新视野号可能会进入际空间，在那里它将对层外的空间进行详细研究。
