Named as a tribute to Edwin Hubble, was launched into orbit on 24 April 1990 as a joint project of NASA and ESA, thus inaugurating the Great Observatories program. Cylindrically shaped Hubble weighs 11 tons. Its length is 13.2 m and its maximum diameter is 4.2 meters. The telescope can obtain images with higher optical resolution 0.1 seconds of arc. 哈勃太空望远镜是一个位於外大气层的机器人望远镜，在海拔五百九十三公里的环形轨道上围绕地球，轨道周期为96和97分钟，它以2.8万公里的时速沿太空轨道运行 ，命名埃德温 哈勃。 作为美国航太局和欧空局的一个联合项目，1990年4月24日哈勃太空望远镜发射进入轨道，从而开创了大天文台进程。圆柱状哈勃太空望远镜重量11吨。其长度为13.2米，最大直径为4.2米。 这架望远镜能够获得更高的光学图像的0.1弧秒的角分辨率 。 The International Space Station 国际航空站 View from inside the ship 从舱內鸟瞰地球 Hubble 哈勃太空望远镜 First we see the Galaxy Hat, also called M 104 in the Messier catalog, distance of about 28 million light-years it is considered the best photograph taken by Hubble. 首先，我们看到银河系红帽，在梅西尔目录也称为M 104，距离约为28万光年它被认为是最好的照片由哈勃拍摄。 Now the famous nebula MZ3, called Formic, between 3000 and 6000 light years. 現在是著名的MZ3星云 ，被称为蚂蚁星云 ， 距离为3000和6000光年之間。 Third is the Eskimo Nebula NGC 2392 located 5000 light years. 第三次是爱斯基摩星云NGC 2392，星系距离5000光年。?
