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，可以看到一团剧烈而混乱的气体和灰尘。这个天体被称为N 63A，是一颗大质量恒星的残骸，它爆炸后将其气态层喷出到一个已经很混乱的区域。 The supernova remnant is part of a star-forming region in the Large Magellanic Cloud (LMC), an irregular galaxy 160,000 light-years from our own Milky Way. 这颗超新星遗迹是大麦哲伦星云 (LMC) 中恒星形成区的一部分，这是一个距离我们银河系160,000光年的不规则星系。 Supernova remnants have long been thought to set off episodes of star formation when their expanding shock encounters nearby gas. N 63A is still young, and its ruthless shocks are destroying the ambient gas clouds, rather than coercing them to collapse and form stars. 长期以来，人们一直认为超新星遗迹在其膨胀的冲击力遇到附近的气体时，会引发恒星的形成。N 63A仍然很年轻，它无情的冲击正在摧毁周围的气体云，而不是胁迫它们坍缩并形成恒星。 Image Credit: NASA/ESA/HEIC…

哈勃望远镜探测到危险的舞蹈

ByNASA中文

This NASA/ESA Hubble Space Telescope image features two interacting galaxies that are so intertwined, they have a collective name – Arp 91. Their delicate galactic dance takes place more than 100 million light-years from Earth. The two galaxies comprising Arp 91 have their own names: the lower galaxy, which looks like a bright spot, is NGC 5953, and the oval-shaped galaxy to the upper right is NGC 5954. In reality, both of them are spiral galaxies, but their shapes appear very different because of their orientation with respect to Earth. 这张NASA/ESA哈勃太空望远镜的图片展示了两个相互作用的星系，它们交织在一起，有一个共同的名字——Arp 91。它们微妙的星系之舞发生在距离地球1亿多光年的地方。组成Arp 91的两个星系都有自己的名字：下面的星系，看起来像一个亮点，是NGC 5953，右上方的椭圆形星系是NGC 5954。实际上，这两个星系都是螺旋星系，但是由于它们相对于地球的方向不同，因此它们的形状看起来非常不同。 Arp 91 provides a particularly vivid example of galactic interaction. NGC 5953 is clearly tugging at NGC 5954, which looks like it is extending one spiral arm downward. The immense…

一颗类似木星的流浪行星在太空中独自游荡

This artist’s conception illustrates a Jupiter-like planet alone in the dark of space, floating freely without a parent star. 这幅艺术家的构思图说明了一颗类似木星的行星在黑暗的太空中独自游荡，没有母星。 Exoplanet hunters have found thousands of planets, most orbiting close to their host stars, but relatively few alien worlds have been detected that float freely through the galaxy as so-called rogue planets, not bound to any star. Many astronomers believe that these planets are more common than we know, but that our planet-finding techniques haven’t been up to the task of locating them. 系外行星猎人已经发现了数以千计的行星，大多数都在靠近其母星的轨道上运行，但相对而言，很少有外星世界被发现，它们作为所谓的流氓行星在星系中自由漂浮，不受任何恒星的约束。许多天文学家认为，这些行星比我们所知道的更常见，但我们的行星寻找技术还没有完成定位它们的任务。 A planet survey, called the Microlensing Observations in Astrophysics (MOA), scanned the central bulge of our Milky Way galaxy from 2006 to 2007. It used a 5.9-foot (1.8-meter) telescope at Mount John University Observatory in New Zealand, and a technique called…

普赛克的小行星任务：电力推进的时代来临了

ByNASA中文

When it comes time for NASA’s Psyche spacecraft to power itself through deep space, it’ll be more brain than brawn that does the work. Once the stuff of science fiction, the efficient and quiet power of electric propulsion will provide the force that propels the Psyche spacecraft all the way to the main asteroid belt between Mars and Jupiter. The orbiter’s target is a metal-rich asteroid also called Psyche. 当NASA的普赛克航天器在深空为自己提供动力时，完成这项工作的将是大脑而不是肌肉。曾经是科幻小说中的东西，高效和安静的电力推进将提供力量，推动普赛克航天器一直到火星和木星之间的主要小行星带。轨道飞行器的目标是一颗富含金属的小行星，也称为普赛克。 The photo on the left captures an operating electric Hall thruster identical to those that will propel NASA’s Psyche spacecraft, which is set to launch in August 2022 and travel to the main asteroid belt between Mars and Jupiter. The xenon plasma emits a blue glow as the thruster operates. The photo on the right…

So, in the late 1950s, NASA and the U.S. Naval School of Aviation Medicine established a joint research program to study these effects and recruited 11 deaf men aged 25-48 from Gallaudet College (now Gallaudet University). Today, these men are known to history as the “Gallaudet Eleven.” 在将人类送入太空之前，NASA需要更好地了解长期失重对人体的影响。因此，在20世纪50年代末，美国宇航局和美国海军航空医学院建立了一个联合研究计划来研究这些影响，并从加劳德特学院（现在的加劳德特大学）招募了11名25-48岁的聋哑人。今天，这些人被历史称为 “加劳德特11人”。 In this image, the study participants chat in the zero-g aircraft that flew out of Naval Air Station in Pensacola, Fla. 在这张图片中，研究参与者在从佛罗里达州彭萨科拉海军航空站起飞的零重力飞机上聊天。 In 2017, Gallaudet University and NASA celebrated the achievements…
