Fingery blobs in a famous Hubble image of the Eagle Nebula show this process. T Tauri variables can result from this process, which occurs in dense areas of dust called Bok globules, and this is driven by the collapse of molecular clouds. The Pillars of Creation display, for 10 points, what process by which objects such as the Sun come into existence?
