NASA的IXPE观测到前所未有的历史性星云
科学家们已经使用IXPE创建了蟹状星云磁场的详细而细致的地图，揭示了比以往更多的内部工作原理。发表在《自然天文学》杂志上的新结果，有助于解决关于被充分研究的蟹状星云的长期谜团，并为未来的研究提出了新的问题。
船帆座脉冲星风星云在NASA IXPE的新图像中飞行
大约一万年前，船帆座的一颗巨星爆炸发出的光到达了地球。这颗超新星留下了一个被称为脉冲星的致密物体，它在旋转时似乎有规律地变亮，就像一座宇宙灯塔。从这颗脉冲星的表面，出现了以接近光速传播的粒子风，形成了带电粒子和磁场的混乱大杂烩，并与周围的气体相撞。这种现象被称为脉冲星风星云。 这张照片显示了船帆座脉冲星风星云。浅蓝色代表来自NASA X射线成像偏振探测器的X射线偏振数据。粉色和紫色对应于NASA钱德拉X射线天文台的数据，该天文台此前曾多次观测到船帆座。NASA的哈勃太空望远镜拍摄了背景中的恒星。单击此处查看未标记的图像。 影像来源：X射线： (IXPE) NASA/MSFC/Fei Xie & (Chandra) NASA/CXC/SAO；光学：NASA/STScI Hubble/Chandra；由N...
哑铃星云发出光秀
Infrared light surges out from the Dumbbell Nebula, also known as Messier 27, in this Aug. 10, 2011, image from NASA’s Spitzer Space Telescope. This nebula was discovered in 1764 by Charles Messier. It was the first in a class of objects, now known as planetary nebulae, to make it into Messier’s catalog of astronomical objects. Planetary nebulae, histo...
哈勃对狼蛛星云的新观察
A snapshot of the Tarantula Nebula (also known as 30 Doradus) is featured in this image from the NASA/ESA Hubble Space Telescope. The Tarantula Nebula is a large star-forming region of ionized hydrogen gas that lies 161,000 light-years from Earth in the Large Magellanic Cloud, and its turbulent clouds of gas and dust appear to swirl between the region’s brig...
哈勃观测到猎户座星云中的双星
The bright variable star V 372 Orionis takes center stage in this image from the NASA/ESA Hubble Space Telescope, which has also captured a smaller companion star in the upper left of this image. Both stars lie in the Orion Nebula, a colossal region of star formation roughly 1,450 light-years from Earth. V 372 Orionis is a particular type of variable star kn...
韦伯在船底星云中发现了年轻恒星的爆发
By taking a closer look at one of Webb’s first images, the iconic Cosmic Cliffs, scientists have found dozens of energetic jets and outflows from young stars previously hidden by dust clouds. The discovery marks the beginning of a new era of investigating how stars like our Sun form, and how the radiation from nearby massive stars might affect the developmen...
哈勃望远镜观测到一个布满恒星的宇宙云
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...
NASA的詹姆斯·韦伯太空望远镜揭开了年轻恒星形成初期的面纱
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。
NASA的詹姆斯·韦伯太空望远镜显示了几颗恒星“搅动”了南环星云
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。
