小型(但功能强大)气象仪器

The Compact Ocean Wind Vector Radiometer (COWVR) is no bigger than a minifridge. The Temporal Experiment for Storms and Tropical Systems (TEMPEST) is even smaller – about the size of a cereal box. Yet these two compact science instruments are designed to do a big job: to make the same high-quality atmospheric observations as weather satellites many times the...

看冬至

The Earth’s solstices come twice a year. For the Northern Hemisphere, the summer (June) solstice occurs around June 20-21, and the winter (December) solstice happens around Dec. 21-22. 地球的至日一年有两次。对于北半球来说,夏至发生在6月20-21日左右,冬至发生在12月21-22日左右。 At the solstice, the Sun’s path appears farthest north or south, depending on which half of the planet you are on. S...

詹姆斯·韦伯太空望远镜的蓝图

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, ...

哈勃望远镜观测到一个有着爆炸历史的星系

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...

反射的星光

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...

尤金·帕克观看以他的名义命名的任务的升空

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...

宇宙交付——NASA收到小行星龙宫的样本
