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...
2023年8月23日 The Meteor and the Galaxy Credit & Copyright: Jose Pedrero Explanation: It came from outer space. It — in this case a sand-sized bit of a comet nucleus — was likely ejected many years ago from Sun-orbiting Comet Swift-Tuttle, but then continued to orbit the Sun alone. When the Earth crossed through this orbit, the piece of comet d...
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 interac...
NASA詹姆斯·韦伯太空望远镜跟踪了哈勃太空望远镜对宇宙大爆炸后10亿年内最遥远的恒星的观测。
一张名为“El Gordo”的星系团的新图像揭示了以前从未见过的遥远的尘埃物体，并提供了大量新的科学证据。这幅红外图像由NASA的詹姆斯·韦伯太空望远镜拍摄，显示了各种不寻常的、扭曲的背景星系，这些星系只在之前的哈勃太空望远镜图像中有所暗示。
这架望远镜拍下了一片闪烁的恒星区域的照片，表明它在离开地球100万英里的旅程后表现良好。
The tranquil spiral galaxy UGC 12295 basks leisurely in this image from the NASA/ESA Hubble Space Telescope. This galaxy lies around 192 million light-years away in the constellation Pisces and is almost face-on when viewed from Earth, displaying a bright central bar and tightly wound spiral arms. Despite its tranquil appearance, UGC 12295 played host to a c...
2023年7月27日 Galaxies in the River Image Credit & License: CTIO/NOIRLab/DOE/NSF/AURA; R. Colombari, M. Zamani & D. de Martin (NSF’s NOIRLab) Explanation: Large galaxies grow by eating small ones. Even our own galaxy engages in a sort of galactic cannibalism, absorbing small galaxies that are too close and are captured by the Milky Way’s gravity...
President Joe Biden unveiled this image of the galaxy cluster SMACS 0723 during a White House event on July 11, 2022. One year later, the James Webb Space Telescope has changed the way we see the universe. From new views of old subjects to discoveries on the chemical composition of exoplanets, Webb has helped us gather clues about the origins of our own sola...
这段视频是作为CEERS（宇宙演化早期发布科学）调查的一部分拍摄的星系的科学可视化，展示了NASA詹姆斯·韦伯太空望远镜的一项重大任务。
