看,南天上空的极光

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...

火星样品返回的艺术家概念图

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...

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...

露西:灵感和小行星

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...

就像天空中的怪物

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。 T...

哈勃望远镜探测到危险的舞蹈

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...

笑一笑! 你在国际空间站上

On Oct. 4, 2021, the seven-member Expedition 65 crew gathered for a portrait inside the vestibule in between the International Space Station’s Unity module and Tranquility module. In the front row from left are; Commander Thomas Pesquet of the European Space Agency; and NASA astronauts Megan McArthur and Shane Kimbrough. In the back are: Roscosmos cosm...

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-cal...

多彩多姿地离开空间站

In this image from Sept. 30, 2021, the SpaceX Cargo Dragon resupply ship is pictured as it backs away from the International Space Station’s forward-facing international docking adapter. The Cargo Dragon’s beacon lights and a plume from one of its engines during its departure burn made for a colorful show. 这张摄于2021年9月30日的照片中,货运补给龙飞船从国际空间站的前向国际对接适...

普赛克的小行星任务:电力推进的时代来临了

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 t...
