2023年12月29日 Shakespeare in Space Image Credit: NASA, ESA, CSA, STScI Explanation: In 1986, Voyager 2 became the only spacecraft to explore ice giant planet Uranus close up. Still, this newly released image from the NIRCam (Near-Infrared Camera) on the James Webb Space Telescope offers a detailed look at the distant world. The tilted outer planet rotates on i...

De Looze (University of Gent) Explanation: Massive stars in our Milky Way Galaxy live spectacular lives. Collapsing from vast cosmic clouds, their nuclear furnaces ignite and create heavy elements in their ...

詹姆斯·韦伯太空望远镜:英仙座中一颗著名的原恒星

这张来自NASA/ESA/CSA詹姆斯·韦伯太空望远镜拍摄的本月新照片揭示了赫比格-哈罗天体797(HH 797)的复杂细节。赫比格-哈罗天体是新生恒星(被称为原恒星)周围的发光区域,由这些新生恒星喷出的恒星风或气体喷流形成激波,与附近的气体和尘埃高速碰撞时形成。HH 797占据了图像的下半部分,它位于年轻的疏散星团IC 348附近,IC 348位于英仙座暗云复合体的东部边缘附近。图像上方明亮的红外物体被认为是另外两颗原恒星的宿主。 这张照片是由韦伯的近红外相机(NIRCam)拍摄。红外成像在研究新生恒星及其外流方面非常强大,因为最年轻的恒星总是镶嵌在形成它们的气体和尘埃中。恒星外流的红外辐射穿透了遮蔽的气体和尘埃,使赫比格-哈罗天体成为韦伯灵敏红外仪器观测的理想对象。在湍流条件下被激发的分子,包括氢分子和一氧...

M1: 不断扩张的蟹状星云

2023年11月15日 M1: The Incredible Expanding Crab Image Credit: NASA, ESA, CSA, STScI; Jeff Hester (ASU), Allison Loll (ASU), Tea Temim (Princeton University) Explanation: Cataloged as M1, the Crab Nebula is the first on Charles Messier’s famous list of things which are not comets. In fact, the Crab Nebula is now known to be a supernova remnant, an expandi...

2023年11月10日 UHZ1: Distant Galaxy and Black Hole Image Credit: X-ray: NASA/CXC/SAO/Ákos Bogdán; Infrared: NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/L. Frattare & K. Arcand Explanation: Dominated by dark matter, massive cluster of galaxies Abell 2744 is known to some as Pandora’s Cluster. It lies 3.5 billion light-years away toward the cons...

NASA的詹姆斯·韦伯太空望远镜和哈勃太空望远镜联手创造了最丰富多彩的宇宙视图

NASA的詹姆斯·韦伯太空望远镜和哈勃太空望远镜联合起来研究一个被称为MACS0416的膨胀星系团。由此产生的全色图像结合了可见光和红外光,组合成有史以来最全面的宇宙视图之一。MACS0416距离地球约43亿光年,是一对相互碰撞的星系团,它们最终将合并成一个更大的星系团。

M1:蟹状星云

2023年11月9日 M1: The Crab Nebula Image Credit: NASA, ESA, CSA, STScI; Tea Temim (Princeton University) Explanation: The Crab Nebula is cataloged as M1, the first object on Charles Messier’s famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star w...
