“Bubble Worlds” –Milky Way’s Star Incubators


Bubble Worlds


Astronomers have observed two cosmic bubble phenomenon in the Milky Way Galaxy and far beyond. The infrared image from NASA’s Spitzer Space Telescope above shows a cloud of gas and dust full of bubbles, estimated to be 10 to 30 light-years across, which are inflated by wind and radiation from hundreds of thousand of young, massive stars which form from dense clouds of gas and dust. Black veins running throughout the cloud are regions of especially dense cold dust and gas where even more new stars are likely to form.
