It looks like a gigantic hole punched through a cloud, but this spectacular new image from the Hubble Space Telescope<\/a> captures something more complicated: a cosmic cycle of destruction and creation, with one generation of stars tearing apart its birthplace while simultaneously helping a new generation form.<\/p>\n LHA 120-N44 (N44, for short) is a nebula that lies about 160,000 light-years away in the Large Magellanic Cloud, a small galaxy that orbits the Milky Way<\/a>. From Earth, it appears in the constellation Dorado. This enormous, empty-looking region measures roughly 210 by 140 light-years. To put that into context, consider that Alpha Centauri<\/a>, the closest star system to ours, is a mere 4.4 light-years distant. Thanks to that giant, hole-like appearance, this nebula is known as a superbubble, a cavity carved out by a cluster of hot, massive stars near its center.<\/p>\n <\/p>\n Those stars are bent on destruction. Just like our star’s solar wind, which creates auroras<\/a> on Earth and defines the extent of the solar system<\/a>, these stars’ powerful winds blast material into space. Meanwhile, the most massive of these stars eventually explode as supernovas, pushing even more gas aside. The collective radiation from both these old and young stars carves the nebula’s giant cavity.<\/p>\n Latest Videos FromLive Science<\/p>\n So what happened to that expelled gas? Most of it has been pushed outward and compressed into a dense shell of gas and dust surrounding the superbubble. Within that shell, new stars are forming \u202a\u2014\u202c so the same massive stars that destroy the gas cloud that created them also may help to produce their replacements.<\/p>\n This is known as “stellar feedback” \u2014 when massive stars heat, ionize and disperse the gas and dust around them, making star formation impossible in their vicinity. Meanwhile, their winds can squeeze neighboring gas clouds until they become dense enough to collapse under their own gravity and make new stars.<\/p>\n You may like<\/p>\n This Hubble image of N44 contains almost half a million stars, including those in the nebula and some lying along the same line of sight. About 30,000 of them are young stars yet to fuse hydrogen in their cores \u2014 the reaction that powers stars like the sun<\/a>. With so many young protostars not yet hot and dense enough to become full-fledged main-sequence stars, N44 gives astronomers a rare opportunity to attempt an answer to what may seem like a very simple question: how long does it take to make a star?<\/p>\n TOPICS<\/p>\n
