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...
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...
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。

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...
