哈勃观测到星系邻居

The highly irregular galaxy ESO 174-1, which resembles a lonely, hazy cloud against a backdrop of bright stars, dominates this image from the NASA/ESA Hubble Space Telescope. ESO 174-1 lies around 11 million light-years from Earth and consists of a bright cloud of stars and a faint, meandering tendril of dark gas and dust. This image is part of a collection ...

NASA的罗曼和ESA的欧几里得将联手研究暗能量

一台名为欧几里得的新太空望远镜将于7月发射,这是ESA在美国宇航局的资助下完成的一项任务,旨在探索宇宙膨胀加速的原因,即暗能量。到2027年5月,NASA的南希·格雷斯·罗曼太空望远镜将与欧几里得一起,以前所未有的方式探索这个谜题。

哈勃观察到一种宇宙海洋生物

The jellyfish galaxy JO206 trails across this image from the NASA/ESA Hubble Space Telescope, showcasing a colorful star-forming disk surrounded by a pale, luminous cloud of dust. A handful of foreground bright stars with crisscross diffraction spikes stands out against an inky black backdrop at the bottom of the image. JO206 lies over 700 million light-year...

NASA的韦布太空望远镜在栅栏后面窥视

詹姆斯·韦伯太空望远镜拍摄的这张照片上,尘埃和明亮的星团交织在一起。明亮的气体和恒星卷须属于棒旋星系NGC 5068,在这张图片的左上角可以看到它明亮的中央棒状结构——这是由韦伯两台仪器所合成。

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。

哈勃太空望远镜拍摄到异常明亮的相互作用星系

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...
