保护地球，探索宇宙，发现文明
Maestro Piotr Gajewski conducts the National Philharmonic in the world premiere performance of Henry Dehlinger’s “Cosmic Cycles,” in this photo from Thursday, May 11, 2023, as an enhanced color image of Jupiter is displayed above. “Cosmic Cycles: A Space Symphony” is a collaboration between composer Henry Dehlinger, NASA’s Goddard Space Flight Center, and th...
一个科学团队对“迷你海王星”的大气层有了新的了解，这是星系中常见的一类行星，但我们对它知之甚少。
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...
Two neutron stars begin to merge in this illustration, blasting a jet of high-speed particles and producing a cloud of debris. These gamma-ray bursts (GRBs) are the most powerful events in the universe. Scientists think these kinds of events are factories for a significant portion of the universe’s heavy elements, including gold. They based their estimates o...
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。
天文学家已经确定，超新星爆炸对行星及其大气构成了另一种威胁。这一结果来自于NASA钱德拉X射线天文台和其他望远镜对30多颗超新星进行的X射线观测分析。
天文学家正在庆祝NASA的哈勃太空望远镜发射33周年，并拍摄了一张附近恒星形成区域NGC 1333的空灵照片。该星云位于英仙座分子云中，距离地球约960光年。
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。
