保护地球，探索宇宙，发现文明
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 fr...
On Oct. 8, 2014, active regions on our Sun gave it the appearance of a jack-o’-lantern. This image is a blend of 171 and 193 angstrom light as captured by the Solar Dynamics Observatory. 2014年10月8日，太阳的活跃区域让它看起来像一个南瓜灯。这张照片是由太阳动力学天文台捕捉到的171埃和193埃的光混合而成。 Image Credit: NASA/GSFC/SDO 图片来源：NASA/GSFC/SDO
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 Zole...
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/ES...
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 conductin...
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...
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...
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 sample...
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...
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 asteroid Patroclus/Menoetius, Eurybates, Orus, Leucus, Polyme...
