Звездные пузыри

Массивные звезды могут пускать пузыри. На изображении показан, возможно, самый известный из всех звездных пузырей, NGC 7635, также известный как туманность Пузырь. Хотя пузырь диаметром 7 световых лет выглядит хрупким, он свидетельствует о бурных процессах, происходящих в нем. Над и слева от центра Пузыря находится горячая звезда О-типа, в несколько сотен тысяч раз более яркая и примерно в 45 раз более массивная, чем Солнце. Яростный звездный ветер и интенсивное излучение этой звезды взорвали структуру светящегося газа против более плотного материала в окружающем молекулярном облаке. Интригующая туманность Пузырь и связанный с ней облачный комплекс находятся всего в 7100 световых годах от нас в направлении хвастливого созвездия Кассиопеи. Этот четкий, дразнящий вид космического пузыря представляет собой переобработанный композит из ранее полученных данных изображений, полученных космическим телескопом Хаббла. Сюрприз на день рождения: какая картинка была на Астрономической картинке дня в твой день рождения? (после 1995 г.)
