If you could send a message to an alien civilization, what would you say? The people from the Cosmic Call project sent the above image as the first page of a longer message. The message was broadcast toward local stars by radio telescope during the summer of 1999. Another message was sent in 2003. The single-dish, 70 meter diameter telescope that send the messages is located in Ukraine on the Crimean peninsula near the town of of Evpatoria. This first page of the Cosmic Call 1999 message, shown above, involves only numbers and so is easier for puzzle solvers to decode than a more famous message broadcast toward distant star cluster M13 in 1974. (The solution is here.)
如果你能发一条信息给地外文明，你会说什么呢?来自宇宙呼唤项目的人们把上面的那幅图片作为一则很长信息的第一页发送出去。信息在1999的夏天里通过射电望远镜发向银河系里的恒星。另外一则则在2003年发送出去。发送信息的70米直径的望远镜位于克里米亚半岛的乌克兰Evpatoria镇附近。宇宙电话1999信息的第一页，展示于上面，仅包括了数字因而它相对1974年发送到远方的星团M31的著名信息更容易被解谜者解码。( 解答是 这里.)
