The teeming stars of the globular cluster NGC 6544 glisten in this image from the NASA/ESA Hubble Space Telescope. This cluster of tightly bound stars lies more than 8,000 light-years away from Earth and is, like all globular clusters, a densely populated region of tens of thousands of stars. This image of NGC 6544 combines data from two of Hubble’s instrume...
在早期宇宙中，恒星和星系之间的气体是不透明的——高能的星光无法穿透它。但是在宇宙大爆炸10亿年后，这种气体变得完全透明。为什么？NASA的詹姆斯·韦伯太空望远镜的新数据已经确定了原因。
The jellyfish galaxy JO206 trails across this image from the NASA/ESA Hubble Space Telescope, showcasing a colorful star-forming disk surrounded by a pale, luminous cloud of dust. A handful of foreground bright stars with crisscross diffraction spikes stands out against an inky black backdrop at the bottom of the image. JO206 lies over 700 million light-year...
天文学中最基本的问题之一是：第一批恒星和星系是如何形成的？NASA的詹姆斯·韦伯太空望远镜已经为这个问题提供了新的见解。
詹姆斯·韦伯太空望远镜拍摄的这张照片上，尘埃和明亮的星团交织在一起。明亮的气体和恒星卷须属于棒旋星系NGC 5068，在这张图片的左上角可以看到它明亮的中央棒状结构——这是由韦伯两台仪器所合成。

天文学家利用NASA的哈勃太空望远镜得出了他们所说的迄今为止最有力的证据，证明了一种罕见的“中等大小”黑洞的存在，这种黑洞可能潜伏在距离地球最近的球状星团的中心，距离地球6,000光年。
Scores of baby stars shrouded by dust are revealed in this infrared image of the star-forming region NGC 2174, as seen by NASA’s Spitzer Space Telescope. Some of the clouds in the region resemble the face of a monkey in visible-light images, hence the nebula’s nickname: the “Monkey Head.” However, in infrared images such as this, the monkey...
The densely packed globular cluster NGC 6325 glistens in this image from the NASA/ESA Hubble Space Telescope. This concentrated group of stars lies around 26,000 light-years from Earth in the constellation Ophiuchus. Globular clusters like NGC 6325 are tightly bound collections of stars with anywhere from tens of thousands to millions of members. They can be...
Maestro Piotr Gajewski conducts the National Philharmonic in the world premiere performance of Henry Dehlinger’s “Cosmic Cycles,” in this photo from Thursday, May 11, 2023, as an enhanced color image of Jupiter is displayed above. “Cosmic Cycles: A Space Symphony” is a collaboration between composer Henry Dehlinger, NASA’s Goddard Space Flight Center, and th...
