一艘新的宇宙飞船正在飞往太阳，拍摄太阳南北两极的首批照片。 由欧洲航天局与NASA合作的太阳轨道飞行器（Solar Orbiter）将于美国东部时间2020年2月7日下午11:15从卡纳维拉尔角发射升空。该航天器将利用金星和地球的引力使自己脱离黄道平面——这一区域大致与太阳的赤道平行，所有行星都围绕该区域运行。 “在太阳轨道飞行器之前，所有的太阳成像仪器都在黄道平面内或非常接近黄道平面，”华盛顿特区海军研究实验室的空间科学家罗素·霍华德说，他是太阳轨道飞行器十种仪器之一的首席研究员。“现在，我们可以从上面俯瞰太阳了。” 太阳轨道飞行器高度倾斜轨道的一部分的动画。 来源： ESA/ATG medialab [rml_read_more] “这将是一个未知的世界。”荷兰欧洲空间研究与技术中心(European Sp...
Astronomers using data from NASA’s Chandra X-ray Observatory and other telescopes have put together a detailed map of a rare collision between four galaxy clusters. Eventually all four clusters — each with a mass of at least several hundred trillion times that of the Sun — will merge to form one of the most massive objects in the universe. Galaxy clust...
As NASA pays tribute and says goodbye to the Spitzer Space Telescope, one of agency’s Great Observatories, one of Spitzer’s great discoveries was that of the TRAPPIST-1 star, an ultra-cool dwarf, which has seven Earth-size planets orbiting it. Spitzer, the ground-based TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) telescope, and other...

视频来源：NASA 美国东部时间1月22日星期三下午1点（北京时间1月23日凌晨2点），美国航空航天局（NASA）主办了现场直播节目，用来纪念NASA的斯皮策空间望远镜（Spitzer Space Telescope）留下的深远“遗产”，在贡献了16年惊为天人的无数发现后，斯皮策任务就要在1月30日宣告结束了。 负责斯皮策观测计划的研究人员包括NASA天体物理学主任保罗•赫兹（Paul Hertz），以及来自NASA喷气推进实验室（Jet Propulsion Laboratory，JPL）的斯皮策项目科学家迈克•沃纳（Mike Werner）、天体物理学家法丽莎•莫拉莱斯（Farisa Morales）、现任的任务主管约瑟夫•亨特（Joseph Hunt）和前任任务主管苏珊•多德（Suzanne Dodd）。...
2020 January 27 Comet CG Evaporates Image Credit & License: ESA, Rosetta, NAVCAM Explanation: Where do comet tails come from? There are no obvious places on the nuclei of comets from which the jets that create comet tails emanate. One of the best images of emerging jets is shown in the featured picture, taken in 2015 by ESA’s robotic Rosetta spacec...
公众有机会为美国宇航局的下一个火星探测车投票选出他们最喜欢的名字。这9个候选名字是由“命名探测车”征文比赛产生的，该比赛邀请美国各地从幼儿园到12年级的学生为NASA的火星2020探测车提出合适的名字，并撰写一篇短文。 比赛于去年8月28日开始后，有超过2.8万篇短文被提交。来自全国各地的教育工作者、专业人士和航天爱好者组成了一个由近4700名裁判志愿者组成的多样化小组，他们将候选范围缩小到来自全国各州和各地区的155名合格的半决赛选手。 “成千上万的学生分享了他们的想法，这个名字将使我们的探测车和团队感到自豪。”位于华盛顿的美国宇航局行星科学部主任洛里·格雷兹说。“还有数千名志愿者参与了评选过程。现在，公众有机会参与进来，表达他们对前九强的喜爱之情。” 这幅图描绘了美国宇航局的下一个火星探测器，将于2020年...
All eyes are on south Mississippi with this month’s delivery and installation of NASA’s Space Launch System (SLS) rocket’s first core stage to Stennis Space Center for a milestone Green Run test series prior to its Artemis I flight. The Green Run testing will be the first top-to-bottom integrated testing of the stage’s systems prior to its maiden flight. The...
