The life of a planetary nebula is often chaotic, from the death of its parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion). The oblate
Located in the constellation of Virgo (The Virgin), around 50 million light-years from Earth, the galaxy NGC 4535 is truly a stunning sight to behold. Despite the incredible quality of this image, taken from the NASA/ESA Hubble Space Telescope, NGC 4535 has a hazy, somewhat ghostly, appearance when
2021年01月24日 Massive Nearby Spiral Galaxy NGC 2841 Image Credit: NASA, ESA, Hubble, Subaru; Composition & Copyright: Roberto Colombari Explanation: It is one of the more massive galaxies known. A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellati
2021年01月16日 The Mountains of NGC 2174 Image Credit: NASA, ESA, Hubble Heritage Team (STScI/AURA) Explanation: This fantastic skyscape lies near the edge of NGC 2174 a star forming region about 6,400 light-years away in the nebula-rich constellation of Orion. It follows mountainous clouds of gas and
Thousands of sparkling young stars are nestled within the giant nebula NGC 3603, one of the most massive young star clusters in the Milky Way Galaxy. NGC 3603, a prominent star-forming region in the Carina spiral arm of the Milky Way about 20,000 light-years away, reveals stages in the life cycle of
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
Lying inside our home galaxy, the Milky Way, this Herbig–Haro object is a turbulent birthing ground for new stars in a region known as the Orion B molecular cloud complex, located 1,350 light-years away. Herbig–Haro (HH) objects are bright patches of nebulosity associated with newborn stars that for
