A NASA mission to touch the sun has revealed answers about the closest star's solar winds, which cause the aurora borealis and can affect Earth's communications systems. The Parker Solar Probe has captured information about the solar wind that flows from the sun's coronal holes toward's our ...
The mission has provided a wealth of information about our nearest star. A two-year mission Launched on Oct. 25, 2006, from Cape Canaveral Air Force Station in Florida, the two golf-cart-size telescopes shared a single rocket into space. STEREO Ahead (A) entered an orbit around the sun ...
当年NASA让旅行者1号给外星文明带去了什么讯息?【旅行者号上的黄金唱片,是一张人性的时间胶囊,从1977年出发,寄向遥远的未来】时间回到1977年。那一年,总统是吉米·卡特,经济正在逐渐复苏,石油稀缺。彼时人们的领带很宽,耐心则很少。作为时代的代表,NASA,在那一年发射了两个即使同类标准下也很小很小的探测器,从卡...
The six satellites that make up NASA’s SunRISE mission are each only about the size of a cereal box, flanked by small solar panels. This fleet of six SmallSats will work together to effectively create a much larger radio antenna in space. Credit: Space Dynamics Laboratory/Allison Bills Mon...
【导读】美国国家航空航天局(NASA)的太阳动力学天文台(SDO)为庆祝其在太空的第 10 年,发布了一个令人着迷的太阳延时拍摄视频,该视频使用十年来每小时连续拍摄的恒星图像,将整个太阳周期浓缩为一个小时的镜头。 在过去十年中,NASA 一直关注着太阳,研究太阳如何产生太阳活动并驱动太空天气——太空中影响整个太阳系(包...

Multiple exoplanets -- planets orbiting stars outside our solar system -- were discovered orbiting an M-dwarf star, called GJ 357 in the Hydra constellation. The star is 40% cooler than our sun and only about a third of the sun's mass and size. A study describing the three planets was...
NASA.gov brings you the latest news, images and videos from America's space agency, pioneering the future in space exploration, scientific discovery and aeronautics research.
Gathering such spectra has historically been a difficult process; only about 200 such measurements for these ices were made before the launch of JWST. SPHEREx, in contrast, will make some eight million such observations. Scientists hope that the work will provide a better understanding of the comp...
Also, the spacecraft is receiving updated positional and navigation information and a new automated command sequence for next month, according to NASA. Its second perihelion in April is expected to bring the spacecraft to a distance of about 24 million kilometers from the Sun, over half the pr...
