伽马射线食尸鬼！

ByNASA中文

In the depths of the universe, the cores of two collapsed stars violently merge to release a burst of the deadliest and most powerful form of light, known as gamma rays. These beams of doom are unleashed upon their unfortunate surroundings, shining a million trillion times brighter than the Sun for up to 30 terrifying seconds. No spaceship will shield you from the blinding destruction of the gamma ray ghouls! 在宇宙深处，两颗坍塌恒星的核心剧烈融合，释放出一束最致命、最强大的光，即伽马射线。这些厄运之光被释放到他们不幸的环境中，比太阳还要亮一百万万亿倍，持续时间长达30秒，令人恐惧。没有宇宙飞船能保护你免受伽马射线食尸鬼的毁灭！ Take a tour of some of the most terrifying and mind-blowing destinations in our galaxy … and beyond. After a visit to these nightmare worlds, you may never want to leave Earth again! You can also download our free posters – based on real NASA science – if you dare. Read More! 参观我们银河系中一些最可怕和最令人震惊的目的地……以及更远的地方。在参观了这些噩梦般的世界之后，你可能再也不想离开地球了。如果您有胆量，您还可以下载我们基于真实NASA科学的免费海报。阅读更多！ Image…

小行星龙宫的样本

ByNASA中文

In June 2021, NASA received its first sample of asteroid Ryugu, which was returned to Earth in December 2020 by the Japan Aerospace Exploration Agency’s (JAXA) Hayabusa2 spacecraft. This is one of the first samples to leave Japan for preliminary investigation. As deputy leader of the mineralogy-petrology subteam for the preliminary analysis effort, Mike Zolensky was one of the first scientists to examine the sample to determine its basic nature. Alongside Zolensky, Jangmi Han from the Astromaterials Research and Exploration Science Division, and James Martinez of the Structural Engineering Division at NASA’s Johnson Space Center in Houston worked together to complete an investigation of the sample. Sample analyses were performed in the Scanning Electron Microscopy Lab in Johnson’s Structural Engineering Division. This was successfully completed…

This celestial lightsaber does not lie in a galaxy far, far away, but rather inside our home galaxy, the Milky Way. It’s inside a turbulent birthing ground for new stars known as the Orion B molecular cloud complex, located 1,350 light-years away. 这把天体光剑并不在遥远的星系中，而是在我们的家园银河系中。它位于一个名为猎户座B分子云复合体的新恒星的湍流诞生地内，距离我们1,350光年。 Image Credit: NASA/ESA 图片来源：NASA/ESA

Lee esta historia en español aquí. 在这里用西班牙语读这个故事。 Teams at NASA’s Kennedy Space Center in Florida lifted the Orion spacecraft and placed it atop the Space Launch System (SLS) Moon rocket, completing assembly for the Artemis I flight test. The spacecraft, complete with its launch abort system, was secured in place Oct. 21, 2021, and teams will begin conducting a series of tests on the fully assembled Moon rocket, now standing 322 feet tall, ahead of launch. The mission, known as Artemis I, will pave the way for a future flight test with crew before NASA establishes a regular cadence of more complex missions with astronauts on and around the Moon. With Artemis, the agency will land the first woman and the first person of color…

哈勃拍摄的“熔环”星系照片引发新的研究

哈勃拍摄的“熔环”星系照片引发新的研究

ByNASA中文

The Hubble Space Telescope’s glamour shots of the universe nearly always have a discovery behind them. 哈勃太空望远镜拍摄的迷人的宇宙照片背后几乎都有一个发现。 In this image, a remote galaxy is greatly magnified and distorted by the effects of gravitationally warped space. After its public release, astronomers used the picture to measure the galaxy’s distance of 9.4 billion light-years. This places the galaxy at the peak epoch of star formation in cosmic evolution. 在这张图片中，一个遥远的星系被引力扭曲的空间所放大和扭曲。在公开发布之后，天文学家们利用这张图片测量出这个星系的距离地球94亿光年。这将该星系置于宇宙演化中恒星形成的高峰期。 In this particular snapshot, a science discovery followed the release of a Hubble observation of a striking example of a deep-space optical phenomenon dubbed an “Einstein ring.” The photo was released in December 2020 as an example of one of the largest, nearly complete Einstein rings ever seen. 在这张特殊的快照中，科学家发现了哈勃望远镜观测到的一个被称为“爱因斯坦环”的深空光学现象的惊人例子。张照片于2020年12月发布，是有史以来最大、几乎完整的爱因斯坦环之一。 Image Credit: ESA/Hubble & NASA, S.

A vivid aurora streams over the Earth as the International Space Station orbits 274 miles above the southern Indian Ocean in between Australia and Antarctica. 在澳大利亚和南极洲之间的南印度洋上空，国际空间站环绕274英里的轨道运行，极光在地球上空闪耀。 The station orbits the Earth in about 90 minutes. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets. 国际空间站绕地球轨道一圈大约需要90分钟。在24小时内，空间站将绕地球运行16圈，经历16次日出和日落。 More Space Station Facts 更多关于国际空间站信息 Image Credit: NASA 图片来源：美国国家航空航天局

This illustration shows a concept for a set of future robots working together to ferry back samples from the surface of Mars collected by NASA’s Mars Perseverance rover. 这幅插图显示了一组未来的机器人协同工作，从火星表面运回由NASA的火星毅力号火星车收集的样本的概念。 NASA and the European Space Agency (ESA) are solidifying concepts for a Mars sample return mission that would seek to take the samples of Martian rocks and other materials being collected and stored in sealed tubes by NASA’s Mars Perseverance rover and return the sealed tubes to Earth. NASA和ESA正在巩固火星样本返回任务的概念，该任务将寻求获取由NASA的火星毅力号火星车收集并储存在密封管中的火星岩石和其他材料的样本，并将密封管送回地球。 According to the current concept, NASA would deliver a Mars lander in the vicinity of Jezero Crater, where Perseverance (left) will have collected and cached samples. The Sample Retrieval Lander (right) would carry a NASA rocket (the Mars Ascent Vehicle), along with ESA’s Sample Fetch Rover (center)…

露西任务即将发射，开始研究特洛伊小行星

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 study Jupiter’s Trojan asteroids. Like the mission’s namesake – the fossilized human ancestor, “Lucy,” whose skeleton provided unique insight into humanity’s evolution – Lucy will revolutionize our knowledge of planetary origins and the formation of the solar system. 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。 The Lucy mission is slated to launch on Saturday, Oct. 16, 2021, at 5:43 a.m. EDT. Launch coverage begins on NASA TV at 5 a.m. 露西号任务定于2021年10月16日星期六，美国东部时间上午5:43发射。美国国家航空航天局电视台将在上午5点开始报道发射情况。 Image Credit: NASA/Bill Ingalls 图片来源：美国宇航局/比尔·英格尔斯
