The Hubble Space Telescope captured a crowd of stars that looks rather like a stadium darkened before a show, lit only by the flashbulbs of the audience’s cameras. Yet the many stars of this object, known as Messier 107, are not a fleeting phenomenon, at least by human reckoning of time – […]
Using the unique capabilities of NASA’s Hubble Space Telescope, a team of astronomers has discovered the most energetic outflows ever witnessed in the universe. They emanate from quasars and tear across interstellar space like tsunamis, wreaking havoc on the galaxies in which the quasars live.
一颗绕着一颗336光年远的双星运行的不太可能的行星，可能会为一个离我们更近的星球提供线索：太阳系中一个被称为第九行星的遥远的假设天体。 这张哈勃太空望远镜的影像显示了11颗木星质量的系外行星HD 106906b的一个可能的轨道（虚线椭圆）。这个遥远的世界与它的宿主恒星相距甚远，这些恒星的灿烂光芒在这里被掩盖，以便可以看到这个星球。这颗行星位于其系统的环绕恒星碎片盘之外，类似于我们自己的柯伊伯带，它由海王星以外的小而冰冷的天体组成。碎片盘本身是不对称且扭曲的，这可能是由于任性行星的引力拖曳所致。图像中的其他光点是背景恒星。 影像来源：NASA, ESA, M.

This large expanse of space captured with the Hubble Space Telescope features the galaxy SDSS J225506.80+005839.9. Unlike many other extravagant galaxies and stunning nebulae imaged by Hubble, this galaxy does not have a short, popular name, and is only known by its long name given in the Sloan Digi
2018年，一个国际研究团队使用美国航空航天局（NASA）/欧洲空间局（ESA）的哈勃空间望远镜（Hubble Space Telescope）和其他几个天文台的数据，首次发现了一个缺失大部分暗物质的星系。这个星系位于银河系的邻居鲸鱼座（Cetus）之中，名为NGC1052-DF2，距离我们4500万光年。 NGC 1052-DF2星系的这一奇怪发现，令天文学家倍感意外，因为依据现有的理解，暗物质是当前星系形成和演化模型中的关键组成部分。实际上，如果没有暗物质的存在，原初气团将缺乏足够的引力来开始它的塌陷过程，也就无法并形成新的星系。 在此一年之后，研究人员又发现了另一个缺失暗物质的星系，NG
The solar system might be a lot hairier than we thought. This illustration shows Earth surrounded by theoretical filaments of dark matter called “hairs.” Dark matter is an invisible, mysterious substance that makes up about 27 percent of all matter and energy in the universe. The regular
我们天空中一些最令人惊叹的景象出现在日落时分，阳光穿透云层，形成了由云层的阴影和大气散射的光束形成的明暗混合光线。 研究邻近星系IC 5063的天文学家们被美国宇航局哈勃太空望远镜拍摄的图像所吸引。在这种情况下，从活跃星系耀眼的中心可以看到一束狭窄的明亮光线和阴影。 这张哈勃太空望远镜拍摄的附近活动星系IC 5063的中心图像显示，明亮的光线和来自炽热核心的阴影混合在一起，炽热核心是一个超大质量黑洞的所在地。天文学家认为，围绕黑洞的一圈尘埃物质可能正在将黑洞的阴影投射到太空中。根据他们的设想，这种光和影的相互作用可能会发生在巨黑洞爆炸的光撞击深埋在核心中的尘埃环的时候。光线穿过尘埃环上的缝隙，
Observed with the NASA/ESA Hubble Space Telescope, the faint galaxy featured in this image is known as UGC 12588. Unlike many spiral galaxies, UGC 12588 displays neither a bar of stars across its center nor the classic prominent spiral arm pattern. Instead, to a viewer, its circular, white and mostl
This NASA/ESA Hubble Space Telescope image features the galaxy LRG-3-817, also known as SDSS J090122.37+181432.3. The galaxy, its image distorted by the effects of gravitational lensing, appears as a long arc to the left of the central galaxy cluster. Gravitational lensing occurs when a large distri
The galaxy UGCA 193, seen here by the NASA/ESA Hubble Space Telescope, is a galaxy in the constellation of Sextans (the Sextant). Looking rather like a waterfall, UGCA 193 appears to host many young stars, especially in the lower portion of this view, creating a striking blue haze and the sense that
