保护地球，探索宇宙，发现文明
Launched in 1977, the twin Voyager probes are NASA’s longest-operating mission and the only spacecraft ever to explore interstellar space. 45 years on, Voyager 1 and 2 continue to provide us with observations of the farthest reaches of space. Our Voyager 1 spacecraft zoomed toward Jupiter in January and February 1979, capturing hundreds of images of Jupiter ...
This view of Jupiter was taken by Voyager 1. This image was taken through color filters, recombined to produce the color image, and assembled from three black and white negatives by the Image Processing Lab at Jet Propulsion Laboratory. The twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-...
美国国家航空航天局的旅行者2号宇宙飞船在进行了8年半的太阳系之旅后，已经准备好迎接另一次挑战。那是1986年1月24日，很快它就会遇到神秘的第七颗行星，冰冷的天王星。 旅行者2号在1986年1月14日接近天王星时拍摄了这张照片。该行星朦胧的蓝色是由于其大气中的甲烷吸收了红色波长的光。 来源：NASA/JPL-Caltech 在接下来的几个小时里，旅行者2号在距天王星云顶50,600英里(81,433公里)的范围内飞行，收集的数据显示出两个新光环、11个新卫星和零下353华氏度(零下214摄氏度)的温度。该数据集仍然是我们迄今为止对天王星进行的唯一近距离测量。 三十年后，科学家重新分析了这些数据，发现了另一个秘密。 整个宇宙物理学界都不知道，34年前旅行者2号飞越了一个等离子体，这是一个巨大的磁泡，可能把天王星的...
