These blueprints of the James Webb Space Telescope were created as a prop for a video series, but since it was requested, we are offering them as a download! (Look close and you’ll notice some of the smaller text is Latin!) 詹姆斯·韦伯太空望远镜的蓝图是作为一个系列视频的道具而设计，但由于有人要求，我们提供下载！（仔细观察，您会发现一些较小的文本是拉丁文！） Webb is targeted to launch at 7:20 a.m. EST Friday, Dec. 24, ...
In this image, the NASA/ESA Hubble Space Telescope captures a side-on view of NGC 3568, a barred spiral galaxy roughly 57 million light-years from the Milky Way in the constellation Centaurus. In 2014 the light from a supernova explosion in NGC 3568 reached Earth – a sudden flare of light caused by the titanic explosion accompanying the death of a massive st...
This Hubble Space Telescope image captures a portion of the reflection nebula IC 2631, which contains a protostar, the hot, dense core of a forming star that is accumulating gas and dust. Eventually, the protostar may gravitationally gather enough matter to begin nuclear fusion and emit its own energy and starlight. 这张哈勃太空望远镜拍摄的图像捕捉到了反射星云IC2631的一部分，其中包含一颗原恒星...
Dr. Eugene Parker (seated), a pioneer in heliophysics, watched as NASA’s Parker Solar Probe launched at 3:31 a.m. EDT on Sunday, Aug. 12, 2018. This was the first agency mission named for a living person. 2018年8月12日星期日，美国东部时间凌晨3:31，太阳物理学先驱尤金·帕克博士（坐着）观看了美国宇航局的帕克太阳探测器发射。这是第一个以在世者命名的NASA任务。 In 2021, the mission performed the closest-ever observations of a...
In this image, a Hayabusa2 sample canister containing sample fragments of the asteroid Ryugu was transferred from JAXA, the Japan Aerospace Exploration Agency, to NASA on Nov. 30, 2021. 在这张图片中，一个隼鸟2号内含龙宫小行星样本碎片的样品罐，于2021年11月30日从日本宇宙航空研究开发机构（JAXA）转移到NASA。 Scientists at ARES, the Astromaterials Research and Exploration Science Division at the Johnson Space Cen...
Each December the Geminids meteor showers appear in the night sky. The 2021 showers are currently active until Dec. 17 and will peak on the night of Dec. 13 into the morning of Dec. 14, making those hours the best time for viewing the meteor shower. 每年12月，双子座流星雨都会出现在夜空中。2021年流星雨将持续到12月17日，并将在12月13日晚至14日上午达到高峰，因此这段时间是观赏流星雨的最佳时间。 The Geminids are caused by deb...
Snoopy, the Zero G Indicator for the Artemis I mission, was delivered to NASA’s Kennedy Space Center on Dec. 2, 2021, before being loaded into the Orion spacecraft ahead of launch early next year. Zero gravity indicators are small items carried aboard spacecraft that provide a visual indicator when a spacecraft has reached the weightlessness of microgravity....
A SpaceX Falcon 9 rocket launches with NASA’s Imaging X-ray Polarimetry Explorer, or IXPE, spacecraft onboard from Launch Complex 39A, Thursday, Dec. 9, 2021, at NASA’s Kennedy Space Center in Florida. The IXPE spacecraft is the first satellite dedicated to measuring the polarization of X-rays from a variety of cosmic sources, such as black holes and neutron...
This stunning image captures a small region on the edge of the inky Coalsack Nebula, or Caldwell 99. Caldwell 99 is a dark nebula — a dense cloud of interstellar dust that completely blocks out visible wavelengths of light from objects behind it. The object at the center of the image is a (much smaller) protoplanetary nebula. The protoplanetary nebula phase ...
NASA’s Laser Communications Relay Demonstration, or LCRD, launched aboard a United Launch Alliance Atlas V rocket on the Department of Defense’s Space Test Program 3 mission from Space Launch Complex 41 at Cape Canaveral Space Force Station, Tuesday, Dec. 7, 2021, from NASA’s Kennedy Space Center in Florida. NASA的激光通信中继演示，或LCRD，由联合发射联盟宇宙神Ⅴ型火箭发射，于2021年12月7日星期...
