2022年11月30日 The Light, the Dark, and the Dusty Image Credit & Copyright: Anthony Quintile Explanation: This colorful skyscape spans about four full moons across nebula rich starfields along the plane of our Milky Way Galaxy in the royal northern constellation Cepheus. Near the edge of the region’s massive molecular cloud some 2,400 light-years awa...
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...

有一种全新的、沉浸式的方式，可以通过声音探索NASA詹姆斯·韦伯太空望远镜的首批全色红外图像和数据。听众可以进入船底座星云中宇宙悬崖的复杂声景，探索描绘南环星云的两幅图像的对比色调，并识别热气巨行星WASP-96 b透射光谱中的各个数据点。“音乐进入了我们的情感中心。”多伦多大学的音乐家和物理学教授马特·拉索说。“我们的目标是通过声音让韦伯的图像和数据易于理解——帮助听众创建自己的心理图像。” 一个由科学家、音乐家和盲人和视障人士组成的团队，在韦伯任务和NASA学习宇宙的支持下，致力于调整韦伯的数据。 韦伯的宇宙悬崖可听化 影像来源：图片：NASA、ESA、CSA 和 STScI； 无障碍制作：NASA、ESA、CSA、STScI 和 Kimberly Arcand (CXC/SAO)、Matt Russo 和...
This celestial cloudscape from the NASA/ESA Hubble Space Telescope captures the colorful region in the Orion Nebula surrounding the Herbig-Haro object HH 505. Herbig-Haro objects are luminous regions surrounding newborn stars that form when stellar winds or jets of gas spew from these infant stars creating shockwaves that collide with nearby gas and dust at ...
