哈勃于2019年10月12日拍摄到了距离地球4.2亿公里的鲍里索夫彗星（2I/Borisov），这是这颗彗星迄今为止最清晰的照片。哈勃望远镜揭示了它周围的尘埃；它正朝着太阳落下，将在2019年12月7日到达最近点，届时它将距离太阳两倍日地距离（约3亿公里）。之后它将以双曲线路径绕过太阳，返回星际空间。 Credit: NASA, ESA and D. Jewitt (UCLA) NASA哈勃太空望远镜展示了星际访客鲍里索夫彗星最好的一张照片，其速度和轨迹表明，它来自我们太阳系外。 鲍里索夫彗星是已知通过太阳系的第二个星际天体。2017年，人类发现的第一个星际游客（被命名为奥陌陌，’Oumuamua）在飞离太阳系之前，在距太阳3800万公里的范围内“溜达”。加州大学洛杉矶分校（UCLA）、观测彗星的负...
Many of the best-loved galaxies in the cosmos are remarkably large, close, massive, bright, or beautiful, often with an unusual or intriguing structure or history. However, it takes all kinds to make a universe — as demonstrated by this Hubble image of Messier 110. Messier 110 may not look like much, but it is a fascinating near neighbor of our home galaxy, ...
This image from the NASA/ESA Hubble Space Telescope shows NGC 5307, a planetary nebula that lies about 10,000 light-years from Earth. It can be seen in the constellation Centaurus (the Centaur), which can be seen primarily in the southern hemisphere. A planetary nebula is the final stage of a Sun-like star. As such, planetary nebulas allow us a glimpse into ...
来源：NASA/哈勃 斯皮策空间望远镜（SST）16岁了，2003年8月25日，斯皮策空间望远镜在卡角发射升空。 在过去的16年里，哈勃和斯皮策观察过很多相同的天体，斯皮策空间望远镜在红外光波段观测，哈勃空间望远镜在紫外光，可见光以及近红外波段观测。 上面这段视频是哈勃给斯皮策16岁的生日祝福，里面选取的照片为它们共同观测过的，分别有蟹状星云，雪茄星系M82，猎户座星云，旋涡星系M81，触须星系，风车星系，草帽星系，涡状星系，南风车星系。
This atmospheric image taken with the NASA/ESA Hubble Space Telescope shows a dark, gloomy scene in the constellation of Gemini (the Twins). The subject of this image confused astronomers when it was first studied — rather than being classified as a single object, it was instead recorded as two objects, owing to its symmetrical lobed structure (known as NGC ...
这幅艺术家笔下的插图描绘的是系外行星LHS3844b，其质量是地球的1.3倍，环绕着一颗M矮星运行。根据美国国家航空航天局（NASA）斯皮策太空望远镜的观测表明，该行星表面可能主要被黑暗的熔岩覆盖，没有明显的大气层。 版权：NASA /加州理工学院喷气推进实验室（JPL-Caltech）/R. Hurt（红外数据处理与分析中心，IPAC） 一项利用NASA斯皮策太空望远镜的数据进行的新研究提供了一个难得的机会，使我们得以一窥围绕太阳之外的恒星运行的岩质行星表面的情况。8月19日发表在《自然》（Nature）杂志上的这项研究表明，该行星的表面可能类似于地球的卫星月球或者水星：该行星可能几乎没有大气层，可能被在月球表面黑暗区域（mare）发现的同样的冷却火山物质所覆盖。 LHS 3844b行星于2018年由NASA...
Although it looks more like an entity seen through a microscope than a telescope, this rounded object, named NGC 2022, is certainly not algae or tiny, blobby jellyfish. Instead, it is a vast orb of gas in space, cast off by an aging star. The star is visible in the orb’s center, shining through the gases it formerly held onto for most of its stellar li...
2019 August 11 Arp 87: Merging Galaxies from Hubble Image Credit: NASA, ESA, Hubble Heritage Team (STScI, AURA) Explanation: This dance is to the death. Along the way, as these two large galaxies duel, a cosmic bridge of stars, gas, and dust currently stretches over 75,000 light-years and joins them. The bridge itself is strong evidence that these two immens...
The pair of strange, luminescent creatures at play in this image are actually galaxies — realms of millions upon millions of stars. This galactic duo is known as UGC 2369. The galaxies are interacting, meaning that their mutual gravitational attraction is pulling them closer and closer together and distorting their shapes in the process. A tenuous bridge of ...
This new Hubble Space Telescope view of Jupiter, taken on June 27, 2019, reveals the giant planet’s trademark Great Red Spot, and a more intense color palette in the clouds swirling in Jupiter’s turbulent atmosphere than seen in previous years. The colors, and their changes, provide important clues to ongoing processes in Jupiter’s atmosphe...
