Summary

Description Chandra image of Sgr A.jpg	English: This Chandra image of Sgr A* and the surrounding region is based on data from a series of observations lasting a total of about one million seconds, or almost two weeks. Such a deep observation has given scientists an unprecedented view of the supernova remnant near Sgr A* (known as Sgr A East) and the lobes of hot gas extending for a dozen light years on either side of the black hole . These lobes provide evidence for powerful eruptions occurring several times over the last ten thousand years. The image also contains several mysterious X-ray filaments, some of which may be huge magnetic structures interacting with streams of energetic electrons produced by rapidly spinning neutron stars . Such features are known as pulsar wind nebulas. Русский: ru:Стрелец_A* и прилегающие области. Изображение получено телескопом Чандра путём объединения многократных экспозиций с общим временем в один миллион секунд, или почти две недели непрерывного времени съёмки. Таким способом достигнуто беспрецедентное изображение остатков сверхновой около ru:Стрелец_A* , известная как Стрелец_A восточная. Видны "лепестки" из горячего газа, расширившегося на расстояние в несколько световых лет по ту же сторону от чёрной дыры . Эти "лепестки" являются очевидными свидетельствами мощных разрушений, случавшихся несколько раз за последние 10 тысяч лет. Изображение также содержит несколько "загадочных" , некоторые из которых могут быть гигантскими магнитными структурами взаимодействующими с потоками высокоэнергетических электронов, испущенными быстро вращающимися нейтронными звёздами. Это явление известно как...
