这张照片拍摄于2021年10月16日星期六，佛罗里达州卡纳维拉尔角空军基地，美国联合发射联盟的宇宙神Ⅴ号火箭搭载露西航天器，从41号航天发射场发射升空，曝光时间为2分30秒。露西号将是第一个研究木星特洛伊小行星的航天器。就像这项任务的名字一样——人类祖先的化石“露西”，其骨骼为人类的进化提供了独特的见解——露西将彻底改变我们对行星起源和太阳系形成的认识。 影像来源：NASA/Bill Ingalls 美国宇航局的露西任务是该机构首次前往木星特洛伊小行星的任务，于美国东部时间周六上午5:34由联合发射联盟（ULA）的宇宙神Ⅴ号火箭从佛罗里达州卡纳维拉尔角空军基地的太空发射场发射。 在接下来的12 […]

With the Lucy spacecraft aboard, a United Launch Alliance Atlas V rocket is seen as it is rolled out of the Vertical Integration Facility to the launch pad at Space Launch Complex 41, Thursday, Oct. 14, 2021, at Cape Canaveral Space Force Station in Florida. Lucy will be the first spacecraft to stud
2021年10月15日 NGC 289: Swirl in the Southern Sky Image Credit & Copyright: Mike Selby Explanation: About 70 million light-years distant, gorgeous spiral galaxy NGC 289 is larger than our own Milky Way. Seen nearly face-on, its bright core and colorful central disk give way to remarkably faint, bl
美国国家航空航天局（NASA）和欧洲航天局（European Space Agency, ESA）正在开展一项活动，将火星样本送回地球。 9月1日，NASA的毅力号火星车展开了它的机械臂，将一个钻头放在火星表面，并向下钻了大约2英寸（6厘米），以提取一个岩石核心。火星车后来将岩芯密封在样本管内。这一历史性事件标志着航天器首次从另一颗行星收集岩石样本，这些样本可以由未来的航天器返回地球。 火星样本返回是一个多任务活动，旨在检索坚毅号将在未来几年内收集的岩心。目前处于概念设计和技术开发阶段，该活动是航天史上最雄心勃勃的努力之一，涉及多个航天器、多次发射和几十个政府机构。 “自20世纪80年代以来，
NASA’s Lucy mission will explore a record-breaking number of asteroids, flying by one asteroid in the solar system’s main asteroid belt, and by seven Trojan asteroids. 美国宇航局的露西任务将探索破纪录的小行星，飞过太阳系主小行星带的一颗小行星，以及七颗特洛伊小行星。 This illustration is of the Lucy mission’s seven targets: the binary a
2021年10月14日 NGC 7293: The Helix Nebula Image Credit & Copyright: Ignacio Diaz Bobillo Explanation: A mere seven hundred light years from Earth, toward the constellation Aquarius, a sun-like star is dying. Its last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and
2021年10月13日 NGC 7822: Cosmic Question Mark Image Credit & Copyright: Yizhou Zhang Explanation: It may look like a huge cosmic question mark, but the big question really is how does the bright gas and dark dust tell this nebula’s history of star formation. At the edge of a giant molecular
A violent and chaotic-looking mass of gas and dust is seen in this Hubble Space Telescope image of a nearby supernova remnant. Denoted N 63A, the object is the remains of a massive star that exploded, spewing its gaseous layers out into an already turbulent region. 在这张哈勃太空望远镜拍摄的附近超新星残余物的图像中，可以看到一团剧烈
