Hubble Peers Into a Stellar Nursery<\/h2>\n

Every time I turn around, Hubble Space Telescope is looking at another fantastic place in the cosmos. This time, it’s a massive region of starbirth, where gigantic hot young newborn stars are crowded together in an area where there are even MORE stars are still being\u00a0 created.<\/p>\n

The scene that Hubble imaged<\/a> is 30 Doradus, a starbirth nursery that’s wracked with the turbulent winds and activity that accompany the births of stars in close quarters.\u00a0 The hot blue stars you see in this image are part of a cluster called R136. They are but a few million years old and lie about 170,000 light-years away in the neighboring Large Magellanic Cloud (a companion galaxy to the Milky Way).<\/p>\n

Many of these icy blue stars are among the most massive stars known. Several of them are over 100 times more massive than our Sun.\u00a0 They may look pretty now, but in a few million years, they will have spent their nuclear fuel and will start to pop off like firecrackers in giant supernova explosions.<\/p>\n

The clouds surrounding these stars are being carved away by relentless and prodigious amounts of ultraviolet radiation and stellar winds pouring off the hot young stellar beauties.\u00a0 That action is etching away at the enveloping hydrogen gas cloud in which the stars were born — and, in the process, in some places it may well be choking off the materials that other stars that need to form in the future.<\/p>\n

Now, the stellar winds and radiation aren’t the only action going on here. The motion of the Large Magellanic Cloud itself may have played a huge role in starting the whole star-birth process in 30 Doradus.\u00a0 First, the gravitational tug of the Milky Way and the companion Small Magellanic Cloud may have acted together to push the gas clouds in the LMC together.\u00a0 You need highly compressed clouds of gas and dust to start the stellar nursery chugging away cranking out new stars.<\/p>\n

It’s also likely that when the Large Magellanic Cloud plowed through the halo of the Milky Way in the distant past, that action could also have compressed clouds of gas and dust, setting the stage for star formation. As fascinating as this is because it’s happening relatively near to our galaxy, this same scene has played itself out many times through out the early history of the universe. In distant regions where galaxies have collided, massive clusters like R136 are common and this tells us that glaaxy interactions are a great spur to star birth.\u00a0 This image is a great example of studying something close to us that gives us great insight into something that happened in galaxies long ago and far, far away.<\/p>\n","protected":false},"excerpt":{"rendered":"
