哈勃太空望远镜拍摄到一个难以捉摸的星系团

A menagerie of interesting astronomical finds are visible in this image from the NASA/ESA Hubble Space Telescope. In addition to several large elliptical galaxies, a ring-shaped galaxy is lurking on the right of the image. A pair of bright stars are also visible at the left of the image, notable for their colorful crisscrossing diffraction spikes. This colle...

SuperBIT观测到碰撞的触须星系

This view of the Antennae Galaxies, two large galaxies colliding 60 million light-years away, is one of the first research images from the Super Pressure Balloon Imaging Telescope (SuperBIT) that launched on a scientific super pressure balloon April 16, 2023 (local time New Zealand). This image and one of the Tarantula Nebula were captured as the balloon-bor...

哈勃望远镜发现一个有卷须的星系

This image taken with the NASA/ESA Hubble Space Telescope shows JO204, a ‘jellyfish galaxy’ so named for the bright tendrils of gas that appear in this image as drifting lazily below JO204’s bright central bulk. The galaxy lies almost 600 million light-years away in the constellation Sextans. Hubble observed JO204 as part of a survey performed with the inten...

钱德拉确定了星系风的成因

利用NASA钱德拉X射线天文台进行的一项新研究显示,从距离地球1140万光年的近邻星系NGC 253中心发出的强风的影响。这种星系风由温度高达数百万度的气体组成,这些气体以X射线的形式发光。每年都有相当于200万个地球质量的热气体从银河系中心吹出。

船帆座脉冲星风星云在NASA IXPE的新图像中飞行

大约一万年前,船帆座的一颗巨星爆炸发出的光到达了地球。这颗超新星留下了一个被称为脉冲星的致密物体,它在旋转时似乎有规律地变亮,就像一座宇宙灯塔。从这颗脉冲星的表面,出现了以接近光速传播的粒子风,形成了带电粒子和磁场的混乱大杂烩,并与周围的气体相撞。这种现象被称为脉冲星风星云。 这张照片显示了船帆座脉冲星风星云。浅蓝色代表来自NASA X射线成像偏振探测器的X射线偏振数据。粉色和紫色对应于NASA钱德拉X射线天文台的数据,该天文台此前曾多次观测到船帆座。NASA的哈勃太空望远镜拍摄了背景中的恒星。单击此处查看未标记的图像。 影像来源:X射线: (IXPE) NASA/MSFC/Fei Xie & (Chandra) NASA/CXC/SAO;光学:NASA/STScI Hubble/Chandra;由N...
