Summary

Description
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...
