阿雷西博天文台位于波多黎各的阿雷西沃山谷中，是世界上最大的单面口径電波望遠鏡，直径达305米，后扩建为350米，由史丹佛國際研究中心、国家科学基金会與康奈尔大学管理。阿雷西博望远镜是固定望远镜，不能转动，只能通过改变天线馈源的位置扫描天空中的一个带状区域。 1974年，为庆祝改造完成，阿雷西博望远镜向距离地球25,000光年的球状星团M13发送了一串由1,679个二进制数字组成的信号，称为阿雷西博信息。如果信息被地外智慧生命所接收並正確解讀，会得到如右图所示的信息，从上到下依次为：用二进制表示的1-10十个数字、DNA所包含的化学元素序号、核苷酸的化学式、DNA的双螺旋形状、人的外形、太阳系的组成、望远镜的口径和波长。向球状星团M13发送信息的原因是其中的恒星分布比较密集，被地外智慧生命接收的可能性较大。 阿雷西博射电望远镜因其壮观的外形受到影视作品的青睐。
