The highly irregular galaxy ESO 174-1, which resembles a lonely, hazy cloud against a backdrop of bright stars, dominates this image from the NASA/ESA Hubble Space Telescope. ESO 174-1 lies around 11 million light-years from Earth and consists of a bright cloud of stars and a faint, meandering tendril of dark gas and dust. This image is part of a collection ...
The teeming stars of the globular cluster NGC 6544 glisten in this image from the NASA/ESA Hubble Space Telescope. This cluster of tightly bound stars lies more than 8,000 light-years away from Earth and is, like all globular clusters, a densely populated region of tens of thousands of stars. This image of NGC 6544 combines data from two of Hubble’s instrume...
The jellyfish galaxy JO206 trails across this image from the NASA/ESA Hubble Space Telescope, showcasing a colorful star-forming disk surrounded by a pale, luminous cloud of dust. A handful of foreground bright stars with crisscross diffraction spikes stands out against an inky black backdrop at the bottom of the image. JO206 lies over 700 million light-year...
天文学家利用NASA的哈勃太空望远镜得出了他们所说的迄今为止最有力的证据，证明了一种罕见的“中等大小”黑洞的存在，这种黑洞可能潜伏在距离地球最近的球状星团的中心，距离地球6,000光年。
The densely packed globular cluster NGC 6325 glistens in this image from the NASA/ESA Hubble Space Telescope. This concentrated group of stars lies around 26,000 light-years from Earth in the constellation Ophiuchus. Globular clusters like NGC 6325 are tightly bound collections of stars with anywhere from tens of thousands to millions of members. They can be...
This new image from NASA’s Hubble Space Telescope shows interacting galaxies known as AM 1214-255. These galaxies contain active galactic nuclei, or AGNs. An AGN is an extraordinarily luminous central region of a galaxy. Its extreme brightness is caused by matter whirling into a supermassive black hole at the galaxy’s heart. Hubble observed the galaxy closes...
A menagerie of interesting astronomical finds are visible in this image from the NASA/ESA Hubble Space Telescope. In addition to several large elliptical galaxies, a ring-shaped galaxy is lurking on the right of the image. A pair of bright stars are also visible at the left of the image, notable for their colorful crisscrossing diffraction spikes. This colle...
天文学家正在庆祝NASA的哈勃太空望远镜发射33周年，并拍摄了一张附近恒星形成区域NGC 1333的空灵照片。该星云位于英仙座分子云中，距离地球约960光年。
This image taken with the NASA/ESA Hubble Space Telescope shows JO204, a ‘jellyfish galaxy’ so named for the bright tendrils of gas that appear in this image as drifting lazily below JO204’s bright central bulk. The galaxy lies almost 600 million light-years away in the constellation Sextans. Hubble observed JO204 as part of a survey performed with the inten...
This image from the NASA/ESA Hubble Space Telescope shows the globular star cluster NGC 2419. Globular clusters are both beautiful and fascinating. They are spherical groups of stars that orbit the center of a galaxy, and in the case of NGC 2419, that galaxy is our own Milky Way. NGC 2419 is around 300,000 light-years from the solar system, in the constellat...
