小朋友們，曾經有一顆年輕的星星叫做HD 61005，它很特別，因為它會吹出一個大大的氣泡，就像泡泡一樣！這顆星星就像我們的太陽，只不過它還年輕，只有一億歲，距離我們約120光年。它的氣泡叫做星際球，它把周圍的塵埃和氣體推開，形成一個大大的圓圓的空間。這個氣泡有多大呢？大約是200倍的地球到太陽的距離！而我們的太陽也有一個氣泡，叫做日球，保護著行星不受宇宙中的輻射。這顆星星的旁邊還有一些星星誕生後留下的殘骸，看起來就像一雙翅膀，所以人們給這顆星星取了個可愛的名字：蛾子星！

Do young stars blow bubbles? The larger view shows a stellar field observed with the Cerro Tololo Inter-American Observatory in Chile, and the inset highlights HD 61005, a star like our Sun, only 120 light-years away. Much younger than the Sun, at just about 100 million years old, it blows a fast and dense stellar wind that pushes out the cooler dust and gas that surrounds it, forming a bubble called an astrosphere. The star-blown bubble was detected with the Chandra X-ray Observatory, and it has a diameter roughly 200 times the Earth-Sun distance. Our Sun has a bubble too, called the heliosphere, which protects the planets from cosmic radiation. Also shown in the inset is debris left behind from star formation, observed by Hubble. The debris appears as wings, giving the star its nickname: the Moth.
