NASA的韦伯拍摄到年轻恒星的超音速外流

这张来自NASA詹姆斯·韦伯太空望远镜的HH 211的照片显示了一颗0级原恒星的外流,这颗原恒星是一颗类似太阳的年前恒星,当时它的年龄不超过几万年,质量只有现在太阳的8%(它最终会成长为一颗像太阳一样的恒星)。

哈勃望远镜发现嵌入银河系内部的闪光球状星团

This colorful image of the globular star cluster Terzan 12 is a spectacular example of how dust in space affects starlight coming from background objects. A globular star cluster is a conglomeration of stars, arranged in a spheroidal shape. Stars in globular clusters are bound together by gravity, with a higher concentration of stars towards the center. The ...

旅行者1号升空,迈向星际之旅

On Sept. 5, 1977, NASA’s Voyager 1 spacecraft lifts off atop its Titan/Centaur-6 launch vehicle from Launch Complex 41 at Cape Canaveral Air Force Station, now Cape Canaveral Space Force Station, in Florida. Voyager 1 and its twin, Voyager 2, were originally launched to conduct closeup studies of Jupiter and Saturn, Saturn’s rings, and the larger...

哈勃看到一个闪亮的临近星系

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...

哈勃望远镜拍摄到宇宙星系团

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...

哈勃望远镜瞥见一个闪烁的星系团

The glittering, glitzy contents of the globular cluster NGC 6652 sparkle in this star-studded image from the NASA/ESA Hubble Space Telescope. The core of the cluster is suffused with the pale blue light of countless stars, and a handful of particularly bright foreground stars are adorned with crisscrossing diffraction spikes. NGC 6652 lies in our own Milky W...

詹姆斯·韦伯太空望远镜聚焦El Gordo星系团中的引力弧

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。
