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

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

2012 年，在开地球 40 年后，航海一飞越了日光层，进入了际领土。

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

在前往日球层边缘的途中，航海一拍摄了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，我们探索和研究了太阳系的外边界，突破了日球层进入际空间。

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.

日球层是太阳磁场边缘围绕我们太阳系的一个“气泡”，它通常定义了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了对年轻太阳系形成的重要一瞥。到 2043 年，新视野可能会进入际空间，在那里它将对日光层外的空间进行详细研究。
