This cloudy, turbulent scene acquired by the Hubble Space Telescope in 2017 shows a stellar nursery within the Large Magellanic Cloud. This nursery, known as N159, contains many hot young stars. These stars emit intense ultraviolet light, which causes nearby hydrogen gas to glow, and torrential stel […]
A little-studied star, TYC 3203-450-1, upstages a galaxy in this Hubble Telescope image from December 2017. Both the star and the galaxy are within the Lizard constellation, Lacerta. However, the star is much closer than the much more distant galaxy. Astronomers studying distant objects call these s
This time lapse of the Milky Way Galaxy taken from the International Space Station (ISS) also captured a lightning strike on Earth so bright that it lit up the space station’s solar panels. Astronaut Kjell Lindgren posted this on Twitter and Instagram on Sept. 2, 2015, saying, “Large lightning
一个巨大的粉红色斑点星系，像一个轮子，内部有一个小的椭圆形的内环，中间是尘土飞扬的蓝色。左边有两个较小的螺旋星系，在黑色背景下大小大致相同。 影像来源：NASA, ESA, CSA, STScI NASA的詹姆斯·韦伯太空望远镜观察了混乱的车轮星系，揭示了有关恒星形成和星系中心黑洞的新细节。韦伯强大的红外观测产生了这张车轮星系和两个较小伴星系的详细图像，背景是许多其他星系。这张图片提供了一个新的视角，展示了车轮星系在数十亿年中是如何变化的。 车轮星系位于约5亿光年外的玉夫座中，是一个罕见的景象。它的外观，很像马车的车轮，这是一个激烈事件的结果——一个大的螺旋星系和一个在这张照片中看不到的小星系
斯蒂芬五重奏（Stephan ‘s Quintet）是由五个星系组成的视觉组合，以其在假日经典电影《Stephan ‘s Quintet》中的突出表现而闻名，NASA的詹姆斯·韦伯太空望远镜以全新的视角揭示了斯蒂芬五重奏。这幅巨大的拼图是韦伯迄今为止拍摄的最大图像，覆盖了月球直径的五分之一。它包含超过1.5亿像素，由近1,000个独立的图像文件构成。来自韦伯的信息为星系相互作用如何推动早期宇宙中的星系演化提供了新的见解。 凭借其强大的红外视觉和极高的空间分辨率，韦伯展现了这个星系群中前所未有的细节。由数百万颗年轻恒星组成的闪闪发光的星团和新恒星诞生的星暴区为这幅图像增光
NASA的詹姆斯·韦伯太空望远镜拍摄了迄今为止最深处、最清晰的遥远宇宙红外图像。这张被称为韦伯第一深场的星系团SMACS0723的图像充满了细节。 数千个星系——包括在红外线中观测到的最微弱的物体——首次出现在韦伯的视野中。这片广阔的宇宙覆盖了一片天空，它的大小和地面上某个人在一臂距离外捧着的一粒沙子差不多。 韦伯的近红外相机（NIRCam）拍摄的这个深场是由不同波长的图像合成而成的，总共耗时12.5小时——在红外波长上达到的深度超过了哈勃太空望远镜需要花费数周时间才能到达最深处的视野。 这张照片显示的是46亿年前出现的星系团SMACS 0723。这个星系团的总质量就像一个引力透镜，放大了它后
This NASA/ESA Hubble Space Telescope observation has captured the galaxy CGCG 396-2, an unusual multi-armed galaxy merger which lies around 520 million light-years from Earth in the constellation Orion. This observation is a gem from the Galaxy Zoo project, a citizen science project involving hundre
The Hubble Space Telescope captured this glittering scene using its Wide Field Camera 3 and Advanced Camera for Surveys. Globular clusters are stable, tightly bound groups of tens of thousands to millions of stars. As this image demonstrates, the hearts of globular clusters are densely packed with s
The brilliant cascade of stars through the middle of this image is the galaxy ESO 318-13 as seen by the Hubble Space Telescope in this image from 2012. Despite being located millions of light-years from Earth, the stars captured in this image are so bright and clear one could almost attempt to count
2022年6月15日 In the Heart of the Virgo Cluster Image Credit & Copyright: Saulius Adomaitis Explanation: The Virgo Cluster of Galaxies is the closest cluster of galaxies to our Milky Way Galaxy. The Virgo Cluster is so close that it spans more than 5 degrees on the sky – about 10 times the a
