Starbirth

The process in which a cloud of interstellar gas and dust collapses to form a new star. The collapse may be triggered by the shockwave from an exploding star, the gravity of a passing star cluster, or some other external source. The process fragments a cloud that may span many light-years into smaller pockets of matter, which collapse under their own gravitational pull. As such a pocket of matter collapses, its core gets hotter and hotter. When it gets hot enough, it triggers the process of nuclear fusion, which powers the newborn star.
