Спутник ФКИ. GALEX. [Редактировать]

С помощью этого ультрафиолетового телескопа 10 лет велись наблюдения за сотнями миллионов галактик. Так, например, астрономам удалось распознать самую большую из известных спиральных галактик во Вселенной, имеющую обозначение NGC 6872, запечатлеть черную дыру в момент поглощения звезды и обнаружить переходную стадию между начальным и конечным этапами эволюционного развития галактик. Результатом наблюдений явилось также и подтверждение того, что темная энергия ускоряет расширение Вселенной. В течение последнего года эксплуатации КА GALEX были зафиксированы ударные волны, вызванные взрывами сверхновых, и осуществлялось наблюдение за изменением ярких активных центров галактик с течением времени. Ученым еще предстоит обработать данные, полученные за последний год выполнения программы. КА GALEX пробудет на орбите 65 лет, перед тем как сгорит в атмосфере Земли.
