NASA-我们银河系的中心是🌌这张2004 @ NASAChandraXRay图像是通过结合十几个观测值制作的
案例简介：我们银河系的中心是🌌这张2004的 @ NASAChandraXRay图像是通过结合银河系中心130光年的区域的十几个观测结果而产生的。钱德拉 (Chandra) 是一种望远镜，旨在检测来自宇宙非常热区域的x射线发射。在这里，明亮的颜色根据其能量水平表示x射线: 低 (红色) 中等 (绿色) 和高 (蓝色)。多亏了钱德拉，天文学家已经能够识别出成千上万的点状x射线源: 中子星，黑洞，白矮星，前景星和背景星系。剩下的是从左上延伸到右下的漫射x射线辉光，沿着星系的圆盘方向。漫射辉光的光谱与包含两个成分的热气体云一致: 1000万摄氏度的气体和10000万度的气体。漫射x射线似乎是沿银河系盘面延伸数千光年的x射线发射脊中最亮的部分。这个山脊的范围意味着在这个图像中弥漫的热气体很可能没有被银河系中心的超大质量黑洞加热。信用: NASA/CXC/UCLA/MIT/M.Muno等人 # NASA # XRays # Galaxy # MilkyWay # 发光

案例简介：The center of our Milky Way galaxy is aglow 🌌This 2004 @NASAChandraXRay image was produced by combining a dozen observations of a region 130 light-years across, in the center of the Milky Way. Chandra is a telescope designed to detect X-ray emissions from very hot regions of the universe. Here, the bright colors represent X-rays according to their energy level: low (red ) medium (green) and high (blue). Thanks to Chandra, astronomers have been able to identify thousands of point-like X-ray sources: neutron stars, black holes, white dwarfs, foreground stars, and background galaxies. What remains is a diffuse X-ray glow extending from the upper left to the lower right, along the direction of the disk of the galaxy.The spectrum of the diffuse glow is consistent with a hot gas cloud that contains two components: 10-million-degree Celsius gas, and 100-million-degree gas. The diffuse X-rays appear to be the brightest part of a ridge of X-ray emission that stretches for several thousand light years along the disk of the galaxy. The extent of this ridge implies that the diffuse hot gas in this image is probably not being heated by the supermassive black hole at the center of the Milky Way.Credit: NASA/CXC/UCLA/MIT/M.Muno et al.#NASA #XRays #Galaxy #MilkyWay #Glowing
