摘要： 旅行者1号和旅行者2号在离开日球层后，继续在星际空间中航行。 先锋10号、先锋11号以及新地平线号飞船也正在接近日鞘的路径上。 这些航天器已经与深空网络（DSN）的无线电天线通信，以下载科学数据和遥测数据。 从DSN向外传输的信息会传送到航天器，并继续向更远的星际空间传播。 这些传输已经遇到并且将来还会遇到其他恒星，这使得其他太阳系中的智能生命有可能接收到我们的地球传输信号。 我们利用DSN与星际航天器之间的波束宽度，在从JPL Horizons系统获得的每个航天器过去和未来的轨道位置周围进行搜索。 通过在Gaia附近恒星目录（GCNS）中进行此搜索，该目录精确绘制了100秒差距范围内的恒星图，我们确定了这些航天器的传输将遇到哪些恒星。 我们突出显示位于DSN传输背景中的恒星，并计算这些相遇的日期，以确定潜在的外星智能生命可能遇到地球传输的时间和地点。 显示英文摘要

摘要： After having left the heliosphere, Voyager 1 and Voyager 2 continue to travel through interstellar space. The Pioneer 10, Pioneer 11, and New Horizons spacecraft are also on paths to pass the heliopause. These spacecraft have communicated with the Deep Station Network (DSN) radio antennas in order to download scientific data and telemetry data. Outward transmissions from DSN travel to the spacecraft and beyond into interstellar space. These transmissions have encountered and will encounter other stars, introducing the possibility that intelligent life in other solar systems will encounter our terrestrial transmissions. We use the beamwidth of the transmissions between DSN and interstellar spacecraft to perform a search around the past and future positions of each spacecraft obtained from the JPL Horizons System. By performing this search over the Gaia Catalogue of Nearby Stars (GCNS), a catalogue of precisely mapped stars within 100 pc, we determine which stars the transmissions of these spacecraft will encounter. We highlight stars that are in the background of DSN transmissions and calculate the dates of these encounters to determine the time and place for potential intelligent extraterrestrial life to encounter terrestrial transmissions.
