来自NASA钱德拉天文台给出的数据展示了名为W28超新星遗迹的新细节，这张大视场遗迹的中心，低能X射线被标为红色，中级能量的X射线为绿色，高能的是蓝色。钱德拉的数据同时也展现了中心高能发射物形状和程度，通过研究W82和其类似天体，天文学家希望能更好的理解当一颗处于拥挤环境中的恒星爆炸时的复杂性
Data from NASA’s Chandra X-ray Observatory give new detail into the heart of supernova remnant W28. In this close-up view of the center of the remnant, low-energy X-rays are colored red, the medium are green, and the highest found by Chandra are blue. The Chandra data show the shape and extent of the high-energy emission in the central region. By studying W28 and others like it, astronomers hope to better understand the complexities involved when a star explodes in a crowded neighborhood.
这张复合图展现了一个名叫W28的经典混合形态的超新星遗迹，每个波长都展示了正在经受冲击波或已经经受过的遗迹的结构细节，目星周围围绕着复杂的星云。背景恒星和良好的结构通过美国CHILE的天文台观测到。射电（橘色）数据由新墨西哥的巨天线阵得到，另外大视野中蓝色标记数据的来自ROSAT卫星
This composite shows a classic example of mixed-morphology supernova remnant known as W28. Each wavelength shows detailed structure of how the supernova shock wave is interacting, or has interacted, with the complex cloudy environment which surrounded its parent star. The background stars and fine structure are seen in optical light (grey and white) by the Cerro Tololo Inter-American Observatory in Chile. The radio (orange) data was obtained by the Very Large Array in New Mexico, while the blue in the wide-field view comes from the ROSAT satellite (X-rays). |
