The Rosette Nebula is not the only cosmic cloud of gas and dust to evoke the imagery of flowers — but it is the most famous. At the edge of a large molecular cloud in Monoceros, some 5,000 light years away, the petals of this rose are actually a stellar nursery whose lovely, symmetric shape is sculpted by the winds and radiation from its central cluster of hot young stars. The stars in the energetic cluster, cataloged as NGC 2244, are only a few million years old, while the central cavity in the Rosette Nebula, cataloged as NGC 2237, is about 50 light-years in diameter. The nebula can be seen firsthand with a small telescope toward the constellation of the Unicorn (Monoceros). Follow APOD on: Facebook, Google Plus, or Twitter

🌹 羅塞特星雲（Rosette Nebula）並非唯一一個喚起花朵意象的宇宙氣體與塵埃雲，但它無疑是最著名的。這個位於保護者（Monoceros）的一個大型分子雲邊緣，距離地球約5,000光年，其「花瓣」實際上是一個恆星誕生區，這種美麗對稱的形狀是受到其中央熱年輕恆星集團的輻射與風的雕刻。這個能量豐富的恆星集團被編號為NGC 2244，年齡僅幾百萬年，而羅塞特星雲的中央空腔（NGC 2237）直徑約50光年。透過小型望遠鏡，可以在位於獨角獸座（Monoceros）方向上親眼觀賞到這個星雲。
