Orbiting more than 200 miles above Earth, the planet we call home, the crew aboard the International Space Station snapped this image of the Earth’s limb, or horizon, with the Sun’s glint beaming off the Pacific Ocean and San Francisco Bay on Nov. 1, 2020.

庆祝国际空间站20周年：远征1号探险队

庆祝国际空间站20周年：远征1号探险队

ByNASA中文

This is the official portrait of the Expedition 1 crew, the first humans to live aboard the International Space Station. Arriving on station on Nov. 2, 2000, they were the first of 64 crews to live and work aboard the orbital laboratory. During a Jan. 30, 1996, press conference in Washington, DC, Vice President Al Gore and Russian Prime Minister Viktor S. Chernomyrdin announced the assignment of American astronaut William M. Shepherd and Russian cosmonaut Sergei K. Krikalev to the first team of crewmembers to occupy the International Space Station (ISS). Shepherd had completed three Space Shuttle missions and Krikalev had flown two long-duration missions aboard the Mir space station as well as on STS-60, becoming the first Russian cosmonaut to fly aboard the Space…

空间站之夜

空间站之夜

ByNASA中文

Night aboard the International Space Station can seemingly look like every spooky sci-fi movie you’ve ever seen. This image shows two empty spacesuits seemingly colluding as most of the astronauts slept. This is one of several images snapped by European Space Agency astronaut Alexander Gerst during his first stay on the orbital laboratory in 2014. During his second stay, he served as Space Station Commander. He has spent nearly a year in space, having served two tours on the station. Image Credit: Alexander Gerst/ESA 在国际空间站上的夜晚看似您所看过的每部怪异的科幻电影。此图显示了两个空的宇航服，它们似乎在大多数宇航员睡觉时缠绕在一起。 这是欧洲航天局宇航员亚历山大·格斯特（Alexander Gerst）在2014年首次留在轨道实验室时拍摄的几张照片之一。在他第二次逗留期间，他曾担任空间站指挥官。他已经在太空待了将近一年，在空间站服役了两次。 图片来源：Alexander Gerst/ESA

我们的万圣节太阳

我们的万圣节太阳

ByNASA中文

Active regions on the sun combined to look something like a jack-o-lantern’s face on Oct. 8, 2014. The active regions appear brighter because those are areas that emit more light and energy — markers of an intense and complex set of magnetic fields hovering in the sun’s atmosphere, the corona. This image blends together two sets of wavelengths at 171 and 193 angstroms, typically colorized in gold and yellow, to create a particularly Halloween-like appearance. This image is a blend of 171 and 193 angstrom light as captured by the Solar Dynamics Observatory. Image Credit: NASA/GSFC/SDO 2014年10月8日，太阳上的活跃区域组合在一起看起来像一个南瓜灯的脸。活动区域显得更亮，因为它们是发出更多光和能量的区域-强烈而复杂的一组磁场的标志盘旋在太阳的大气层—日冕中。这张照片将两组波长分别为171埃和193埃的光线混合在一起，颜色通常为金色和黄色，营造出一种特别万圣节的氛围。 这张照片是由太阳动力学观测台拍摄的171埃和193埃的光线混合而成。 图片来源: NASA/GSFC/SDO

“精灵”在木星的大气中嬉戏

“精灵”在木星的大气中嬉戏

ByNASA中文

This illustration shows the lightning phenomenon known as a sprite and what a sprite could look like in Jupiter’s atmosphere. Named after a mischievous, quick-witted character in English folklore, sprites last for only a few milliseconds. They feature a central blob of light with long tendrils of light extending down toward the ground and upward. In Earth’s upper atmosphere, their interaction with nitrogen give sprites a reddish hue. At Jupiter, where the predominance of hydrogen in the upper atmosphere would likely give them a blue hue. Image Credit: NASA/JPL-Caltech/SwRI 这幅插图展示了被称为精灵的闪电现象，以及精灵在木星大气中的样子。精灵的名字来源于英国民间传说中一个调皮伶俐的角色，它的寿命只有几毫秒。他们的特点是一个中心斑点的光与长长的卷须的光向下延伸到地面和向上。在地球的高层大气中，它们与氮的相互作用使精灵呈现出红色。在木星上，氢在上层大气中占主导地位，可能会使它们呈现出蓝色。 图片来源: NASA/JPL-Caltech/SwRI

NASA astronaut Kate Rubins points to the International Space Station’s “voting booth” where she cast her vote from space this month. This is actually Rubins’ second time to vote from low-Earth orbit, having cast her first vote from space in 2016 when she was an Expedition 48-49 crew member. Voting in space has been possible since 1997 when a bill passed to legally allow voting from space in Texas. Since then, several NASA astronauts have exercised this civic duty from orbit.

This illustration shows Jezero Crater — the landing site of the Mars 2020 Perseverance rover — as it may have looked billions of years go on Mars, when it was a lake. An inlet and outlet are also visible on either side of the lake. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust). Subsequent missions, currently under consideration by NASA in cooperation with the European Space Agency, would send spacecraft to Mars to collect these cached samples…

哈勃看到了银河瀑布

ByNASA中文

In this spectacular image captured by the NASA/ESA Hubble Space Telescope, the galaxy NGC 2799 (on the left) is seemingly being pulled into the center of the galaxy NGC 2798 (on the right). Interacting galaxies, such as these, are so named because of the influence they have on each other, which may eventually result in a merger or a unique formation. Already, these two galaxies have seemingly formed a sideways waterspout, with stars from NGC 2799 appearing to fall into NGC 2798 almost like drops of water. Galactic mergers can take place over several hundred million to over a billion years. While one might think the merger of two galaxies would be catastrophic for the stellar systems within, the sheer amount of space between stars…
