詹姆斯·韦伯太空望远镜揭示了标志性超新星内部的新结构
NASA的詹姆斯·韦伯太空望远镜已经开始研究最著名的超新星之一SN 1987A(超新星1987A)。SN 1987A位于16.8万光年之外的大麦哲伦星云中,自1987年2月被发现以来,近40年来一直是从伽马射线到无线电波长的密集观测目标。

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...
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。
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...
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...
一颗年轻的行星绕着一颗暴躁的红矮星旋转,它的轨道正在以不可预测的方式变化。
NASA的詹姆斯·韦伯太空望远镜在高分辨率近红外光下拍摄了一对正在形成的年轻恒星的“滑稽动作”,这对恒星被称为赫比格-哈罗46/47。
