是什么造成了这个巨大的太空泡沫？被一颗恒星吹来的风吹来，这个诱人的、头状的幽灵被编目为NGC 7635，但简称为气泡星云。这张引人注目的照片利用长时间曝光来揭示这个宇宙气泡及其环境的复杂细节。尽管这个直径10光年的气泡看起来很脆弱，但它提供了剧烈过程在起作用的证据。在气泡中心的右上方，一颗明亮的热恒星镶嵌在星云的反射尘埃中。这颗恒星的质量可能是太阳的10到20倍，猛烈的恒星风和强烈的辐射将发光气体的结构与周围分子云中密度更大的物质炸开。这个迷人的泡泡星云位于距离仙后座仅11000光年的地方。你的天空惊喜：APOD在你的生日上展示了什么照片？(1995后)

What created this huge space bubble? Blown by the wind from a star, this tantalizing, head-like apparition is cataloged as NGC 7635, but known simply as the Bubble Nebula. The featured striking view utilizes a long exposure to reveal the intricate details of this cosmic bubble and its environment. Although it looks delicate, the 10 light-year diameter bubble offers evidence of violent processes at work. Seen here above and right of the Bubble's center, a bright hot star is embedded in the nebula's reflecting dust. A fierce stellar wind and intense radiation from the star, which likely has a mass 10 to 20 times that of the Sun, has blasted out the structure of glowing gas against denser material in a surrounding molecular cloud. The intriguing Bubble Nebula lies a mere 11,000 light-years away toward the boastful constellation Cassiopeia. Your Sky Surprise: What picture did APOD feature on your birthday? (post 1995)
