NASA的韦伯拍摄到年轻恒星的超音速外流
这张来自NASA詹姆斯·韦伯太空望远镜的HH 211的照片显示了一颗0级原恒星的外流，这颗原恒星是一颗类似太阳的年前恒星，当时它的年龄不超过几万年，质量只有现在太阳的8%（它最终会成长为一颗像太阳一样的恒星）。
NASA露西航天器拍摄了第一张小行星丁基什的照片
在恒星背景下移动的小点是NASA的露西航天器首次看到主带小行星丁基什（Dinkish），这是该航天器将在其为期12年的发现之旅中访问的10颗小行星中的第一颗。露西于2023年9月2日和5日拍摄了这两张照片。
哈勃望远镜发现嵌入银河系内部的闪光球状星团
This colorful image of the globular star cluster Terzan 12 is a spectacular example of how dust in space affects starlight coming from background objects. A globular star cluster is a conglomeration of stars, arranged in a spheroidal shape. Stars in globular clusters are bound together by gravity, with a higher concentration of stars towards the center. The Milky Way has about 150 ancient globular clusters at its outskirts. These clusters orbit around the galactic center, but far above and below the pancake-flat plane of our galaxy, like bees buzzing around a hive. The location of this globular cluster, deep in the Milky Way in the constellation Sagittarius, means that it is shrouded in gas and dust which absorb and alter the starlight emanating from…
詹姆斯·韦伯太空望远镜揭示了标志性超新星内部的新结构
NASA的詹姆斯·韦伯太空望远镜已经开始研究最著名的超新星之一SN 1987A（超新星1987A）。SN 1987A位于16.8万光年之外的大麦哲伦星云中，自1987年2月被发现以来，近40年来一直是从伽马射线到无线电波长的密集观测目标。
NASA月球轨道飞行器的数据如何为阿尔忒弥斯宇航员做准备
随着宇航员准备自1972年以来首次重返月球，他们已经接受了如何识别地标、发现地质特征以及帮助标记未来着陆的感兴趣区域的培训，所有这些都使用了LRO收集的数据。
哈勃看到一个闪亮的临近星系
The galaxy ESO 300-16 looms over this image from the NASA/ESA Hubble Space Telescope. This galaxy, which lies 28.7 million light-years from Earth in the constellation Eridanus, is a ghostly assemblage of stars which resembles a sparkling cloud. Other distant galaxies and foreground stars complete this astronomical portrait, which was captured by the Advanced Camera for Surveys. This observation is one of a series which aims to get to know our galactic neighbors. Hubble has observed around three quarters of known galaxies within about 10 megaparsecs of Earth in enough detail to resolve their brightest stars and establish distances to these galaxies. A team of astronomers proposed using small gaps in Hubble’s observing schedule to acquaint ourselves with the remaining quarter of these nearby galaxies….
海王星消失的云层与太阳周期有关
天文学家们发现了海王星云层的增减变化与11年太阳活动周期之间的联系。太阳交织磁场的增强和减弱驱动着太阳活动。
哈勃望远镜拍摄到宇宙星系团
The massive cluster Abell 3322 is featured in this image from the NASA/ESA Hubble Space Telescope, in which the galaxy 2MASX J05101744-4519179 basks in the center. This distant galaxy cluster is a cosmic leviathan that is highly luminous at X-ray wavelengths. Observing galaxy clusters like Abell 3322 can advance our understanding of the evolution and interactions of dark and luminous matter in galaxy clusters, and also reveals powerful gravitational ‘telescopes’ that magnify distant objects through gravitational lensing. Knowing the location of these lenses can enable future observations with both Hubble and the NASA/ESA/CSA James Webb Space Telescope. The galaxy cluster is located in the constellation Pictor, around 2.6 billion light-years from Earth. Two of Hubble’s instruments joined forces to create this image: Wide Field Camera…
