Explanation: Voyager 1 and Voyager 2 were launched in 1977 on a grand tour of the outer planets of the Solar System. They have become the longest operating and most distant spacecraft from Earth. Both have traveled beyond the heliosphere, the realm defined by the influence of the solar wind and the Sun’s magnetic field. On the 45th year of their journey toward the stars Voyager 1 and 2 reached nearly 22 light-hours and 18 light-hours from the Sun respectively and remain the only spacecraft currently exploring interstellar space. Each spacecraft carries a 12-inch gold-plated copper disk with recordings of sounds, pictures and messages. The Golden Records are intended to communicate a story of life and culture on planet Earth, preserved in a medium that can survive an interstellar journey for a billion years.

说明: 旅行者1号和旅行者2号于1977年发射，进行太阳系外围行星的大巡航。它们目前是来自地球，运行时间最久、运转距离最远的航天器。两者皆已穿出了由太阳风和太阳磁场所主宰的日球层。在他们前往恒星旅程的第45年，距离太阳分别将近22光时和18光时的旅行者1号和2号，是目前持续在探索星际空间的唯二航天器。这两个航天器各自携带了一片约30公分直径的镀金铜盘，上面记录着声音、图片和信息。这些黄金唱片旨在传达地球上的生活与文化故事，所使用的记录载体可以在星际旅程中保存10亿年。
