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...
哈勃望远镜凝视着五颜六色的星群
The scattered stars of the globular cluster NGC 6355 are strewn across this image from the NASA/ESA Hubble Space Telescope. NGC 6355 is a galactic globular cluster that resides in our Milky Way galaxy’s inner regions. It is less than 50,000 light-years from Earth in the constellation Ophiuchus. Globular clusters are stable, tightly bound groups of tens...
NASA和SpaceX研究哈勃望远镜重新启动的可能性
更新于2022年12月22日：SpaceX关于重新增强哈勃太空望远镜可能性的非独家研究正在进行中。在2022年12月22日星期四，NASA发布了一份信息征询，以寻求更多有关商业能力的信息，以哈勃作为演示，在轨道上重新装载卫星，无需政府支付任何费用。目前，NASA还没有计划执行或资助专门的哈勃维修任务。信息征询将一直开放到2023年1月24日，NASA将继续探索哈勃未来的选择。
NASA的哈勃望远镜和斯皮策望远镜发现，两颗系外行星主要成分可能是水
由蒙特利尔大学的研究人员领导的一个团队发现了证据，表明围绕一颗红矮星运行的两颗系外行星是“水世界”，水在整个行星中占了很大一部分。这些行星位于天琴座218光年外的一个行星系中，不同于我们太阳系中发现的任何行星。
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...
哈勃望远镜拍摄到壮观的棒状螺旋
Against an inky black backdrop, the blue swirls of spiral galaxy NGC 6956 stand out radiantly. NGC 6956 is a barred spiral galaxy, a common type of spiral galaxy with a bar-shaped structure of stars in its center. This galaxy exists 214 million light-years away in the constellation Delphinus. Scientists used NASA’s Hubble Space Telescope to image NGC 6956 to...
哈勃望远镜发现发射星云双星团
Against a backdrop littered with tiny pinpricks of light glint a few, brighter stars. This whole collection is NGC 1858, an open star cluster in the northwest region of the Large Magellanic Cloud, a satellite galaxy of our Milky Way that boasts an abundance of star-forming regions. NGC 1858 is estimated to be around 10 million years old. Open clusters are a ...
哈勃望远镜观测到一个正在膨胀的宇宙云
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...
哈勃太空望远镜发现神秘的宇宙“钥匙孔”
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...
