詹姆斯·韦伯太空望远镜展示了新星形成和星系演化的区域
2022年10月11日,NASA的詹姆斯·韦伯太空望远镜首次花了20多个小时观测了长期研究的哈勃超深场。一般观测者计划(GO 1963)专注于分析波长在约2微米至4微米之间的领域。

This image from the NASA/ESA Hubble Space Telescope shows the globular star cluster NGC 2419. Globular clusters are both beautiful and fascinating. They are spherical groups of stars that orbit the center of a galaxy, and in the case of NGC 2419, that galaxy is our own Milky Way. NGC 2419 is around 300,000 light-years from the solar system, in the constellat...
有一个看不见的怪物逍遥法外,快速穿过星系间的空间,如果它在我们的太阳系,它可以在14分钟内从地球旅行到月球。
使用NASA的哈勃太空望远镜和其他太空和地面天文台,天文学家调查这些发展取得了意想不到的罕见发现:一对受引力束缚的类星体,都在两个合并的星系中燃烧。
土星巨大的环系统正在加热这颗巨行星的上层大气。这种现象在太阳系中从未出现过。
2022年10月9日,周日,一股强烈的辐射脉冲席卷了太阳系,天文学家很快就把它称为BOAT——有史以来最明亮的辐射。其源头是伽马射线爆(GRB),这是宇宙中最强大的一类爆炸。
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...
天文学家利用NASA的哈勃太空望远镜首次直接测量了一颗孤立白矮星的质量,白矮星是一颗燃烧殆尽的类太阳恒星的残留核心。
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...
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...
