Humanity has only had the technology to hear t...
In a first, astronomers may have seen light from the merger of two black holes, providing opportunities to learn about these mysterious dark objects. 天文学家们首次看到了来自两个黑洞合并产生的光线，为了解这些神秘的黑暗物体提供了机会。 This artist’s concept shows a supermassive black hole surrounded by a disk of gas. Embedded in this disk are two smaller black holes that may have merged togethe...

Weiss et al.; NASA/CXC/CfA/R. Kraft et al.; TANAMI/C. Mueller et al.; EHT/M. Janssen et al. Explanation: How do supermassive black holes create powerful jets? To help find out,...
From 156 million light-years away the heart of active galaxy IC 5063 reveals a mixture of bright rays and dark shadows coming from the blazing core, home of a supermassive black hole. In this Hubble Space Telescope image, astronomers suggest that a ring of dusty material surrounding the black hole may be casting its shadow into space. According to this scena...

Dietrich (Potsdam U. & MPIGP), N. Fischer, S. Ossokine, H. Pfeiffer (MPIGP) Explanation: What happens when a black hole destroys a neutron star? Analyses indicate th...
类星体是非常明亮、遥远、活跃的超大质量黑洞，质量是太阳的数百万到数十亿倍。它们通常位于星系的中心，以坠落的物质为食，并释放出奇妙的辐射洪流。类星体是宇宙中最亮的天体之一，类星体的光芒超过了其所在星系中所有恒星的总和，其喷流和风塑造了它所在的星系。 这是一个以明亮的类星体为中心的星系的艺术概念。类星体是一个非常明亮、遥远、活跃的超大质量黑洞，其质量是太阳的数百万到数十亿倍。类星体是宇宙中最亮的天体之一，类星体的光芒超过了其所在星系中所有恒星的总和。类星体以坠落的物质为食，释放出大量的风和辐射，塑造了它们所在的星系。利用韦伯的独特能力，科学家们将研究宇宙中最遥远、最明亮的6个类星体。 影像来源：NASA, ESA and J.

2021年04月27日 Animation: Black Hole Destroys Star Video Illustration Credit: DESY, Science Communication Lab Explanation: What happens if a star gets too close to a black hole? The black hole can rip it apart — but how? It’s not the high gravitational attraction itself that’s the problem — it’s the difference in gravitational pull...
从空间站安全返回地球… 迎接下一批商业宇航员飞行的宇航员… 以及人类登月系统发展的最新进展… 最近新闻速递，尽在「本周NASA」！ 来源：NASA/JPL-Caltech 翻译：灼眼的粉丝 4月16日，国际空间站的第64号远征队成员——包括NASA的凯特·鲁宾斯，结束了在空间站的工作。在与告别了留在轨道前哨基地上的人员后，鲁宾斯、俄罗斯航天局的谢尔盖·雷日科夫和谢尔盖·库德·斯维尔奇科夫登上了联盟号宇宙飞船返回地球。三人于4月17日上午在哈萨克斯坦安全着陆，此前他们在空间站进行了185天的研究和维护。 4月16日，NASA SpaceX Crew-2空间站任务的宇航员抵达肯尼迪航天中心，在飞往空间站之前，进行最后的发射前活动。Crew-2目前定于4月22日从肯尼迪发射中心39A发射。 NASA宇航员梅根·麦克阿...
Spectacular jets are powered by the gravitational energy of a supermassive black hole in the core of the elliptical galaxy Hercules A. The jets shoot through space for millions of trillions of miles. This image, taken by the Hubble Telescope, was originally released in November 2012. Learn more about black holes: NASA’s Field Guide to Black Holes Image...
2021年04月16日 The Doubly Warped World of Binary Black Holes Scientific Visualization Credit: NASA, Goddard Space Flight Center, Jeremy Schnittman and Brian P. Powell – Text: Francis Reddy Explanation: Light rays from accretion disks around a pair of orbiting supermassive black holes make their way through the warped space-time produced by extreme gravity...
