这些地球人想告诉我们什么？这条特色信息是1974年从地球向球状星团M13广播的。在阿雷西博天文台（当时世界上最大的射电望远镜）升级的奉献仪式上，一串1和0代表了这张图。这种与地外交流的尝试主要是仪式性的——人类经常会无意中向太空发射无线电和电视信号。即使收到这条信息，M13也是如此遥远，我们也要等近5万年才能听到答案。这条特色信息给出了一些关于人类及其知识的简单事实：从左到右是从1到10的数字，包括氢和碳在内的原子，一些有趣的分子，DNA，一个有描述的人，我们太阳系的基础知识，以及发送望远镜的基础知识。对地外智慧的几项搜索目前正在进行中。探索宇宙：随机APOD生成器

What are these Earthlings trying to tell us? The featured message was broadcast from Earth towards the globular star cluster M13 in 1974. During the dedication of an upgrade to the Arecibo Observatory - then the largest single radio telescope in the world - a string of 1's and 0's representing the diagram was sent. This attempt at extraterrestrial communication was mostly ceremonial - humanity regularly broadcasts radio and television signals out into space accidentally. Even were this message received, M13 is so far away we would have to wait almost 50,000 years to hear an answer. The featured message gives a few simple facts about humanity and its knowledge: from left to right are numbers from one to ten, atoms including hydrogen and carbon, some interesting molecules, DNA, a human with description, basics of our Solar System, and basics of the sending telescope. Several searches for extraterrestrial intelligence are currently underway. Explore the Universe: Random APOD Generator
