A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope. NGC 6530 is a collection of several thousand stars lying around 4,350 light-years from Earth in the constellation Sagittarius. The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of...
科学家们“深入研究”韦伯望远镜的首批标志性图像之一，发现了数十个以前被尘埃云隐藏的年轻恒星的高能喷流和外流。这一发现标志着一个新时代的开始，即研究像太阳这样的恒星是如何形成，以及来自附近大质量恒星的辐射如何影响行星的发展。
来自NASA詹姆斯·韦伯太空望远镜的第一批数据显示，至少有两颗，甚至可能有三颗看不见的恒星，塑造了南环星云的形成了南环星云的椭圆形、曲线形。此外，通过将韦伯的红外图像与欧洲航天局（ESA）盖亚天文台的现有数据配对，研究人员第一次能够在形成星云之前精确地确定中心恒星的质量。由澳大利亚悉尼麦考瑞大学的奥索拉·德·马尔科领导的近70名研究人员组成的团队分析了韦伯对这颗垂死恒星的10次高度详细的曝光，得出了这些结果。

A small, dense cloud of gas and dust called CB 130-3 blots out the center of this image from the NASA/ESA Hubble Space Telescope. CB 130-3 is an object known as a dense core, a compact agglomeration of gas and dust. This particular dense core is in the constellation Serpens and seems to billow across a field of background stars. Dense cores like CB 130-3 are...
This peculiar portrait from the NASA/ESA Hubble Space Telescope showcases NGC 1999, a reflection nebula in the constellation Orion. NGC 1999 is around 1,350 light-years from Earth and lies near the Orion Nebula, the closest region of massive star formation to Earth. NGC 1999 itself is a relic of recent star formation – it is composed of debris left over from...
While observing the outer region of the Milky Way galaxy, our Spitzer Telescope captured this infrared image of a cloud of gas and dust that looks like the hollowed-out pumpkins we see every Halloween. Nicknamed the “Jack-o’-Lantern Nebula,” it was likely created by powerful outflows of radiation and particles from a massive O-type star, about 15 to 20 times...
Our James Webb Space Telescope has captured a new image of the famous Pillars of Creation—first imaged by the Hubble Space Telescope in 1995—that reveals new details about the region. The three-dimensional pillars look like majestic rock formations but are far more permeable. These columns are made up of cool interstellar gas and dust that sometimes appear s...
在NASA詹姆斯·韦伯太空望远镜的近红外视图中，创生之柱呈现出万花筒般的色彩。这些柱子看起来像是从沙漠景观中升起的拱门和尖塔，但却充满了半透明的气体和尘埃，而且不断变化。这是一个年轻恒星正在形成的区域，或者说，在它们继续形成的过程中刚刚从它们的尘埃茧中破茧而出。 影像来源：NASA, ESA, CSA, STScI; Joseph DePasquale (STScI), Anton M. Koekemoer (STScI), Alyssa Pagan (STScI). NASA的詹姆斯·韦伯太空望远镜拍摄到了一幅郁郁葱葱、非常详细的景观——标志性的创生之柱，在那里，新的恒星正在稠密的气体云和尘埃云中形成。这些三维柱子看起来像雄伟的岩层，但渗透性更强。这些柱状物由冷的星际气体和尘埃组成，它们有时在近红外光下呈半透...
在这张横跨340光年的拼接图像中，韦伯的近红外相机（NIRCam）以全新的视角展示了狼蛛星云的恒星形成区域，其中包括数以万计从未见过的年轻恒星，这些恒星以前被宇宙尘埃笼罩。最活跃的区域似乎闪烁着巨大的年轻恒星，呈淡蓝色。 影像来源：NASA, ESA, CSA, STScI, Webb ERO Production Team 很久以前，一个宇宙创造的故事展开了：数千颗从未见过的年轻恒星被发现在一个名为剑鱼座30号星云的恒星孕育区，由NASA的詹姆斯·韦伯太空望远镜拍摄。在之前的望远镜图像中，狼蛛星云因其图像中出现的尘埃细丝而被昵称为狼蛛星云，长期以来，该星云一直是研究恒星形成的天文学家的最爱。除了年轻的恒星，韦伯还揭示了遥远的背景星系，以及星云气体和尘埃的详细结构和组成。 狼蛛星云位于大麦哲伦星云星系中，距离我...
