在钱德拉的图像中,“H”代表炽热和巨大
在梅西耶84星系(M84)的热气中有一个“H”形结构。来自银河系中心超大质量黑洞的喷流在高温下产生了相反方向的空洞。NASA钱德拉X射线天文台的X射线数据(以粉红色显示)与VLA的无线电数据(以蓝色显示)相结合,显示了这一点。

This new image from NASA’s Hubble Space Telescope shows interacting galaxies known as AM 1214-255. These galaxies contain active galactic nuclei, or AGNs. An AGN is an extraordinarily luminous central region of a galaxy. Its extreme brightness is caused by matter whirling into a supermassive black hole at the galaxy’s heart. Hubble observed the galaxy closes...
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...
NASA的詹姆斯·韦伯太空望远镜已经开始揭示宇宙历史上迄今为止遥不可及的形成时期:星系的形成和聚集。天文学家称之为红移7.9的距离,即大爆炸后仅6.5亿年,首次证实了由七个星系组成的原星团。
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...
在NASA的詹姆斯·韦伯太空望远镜拍摄的这张照片中,Arp 220就像一座闪耀在星系海洋中的辉煌灯塔,照亮了夜空。实际上,两个螺旋星系在合并的过程中,Arp 220发出最亮的红外光,这使得它成为韦伯的理想目标。
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...
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。
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。
