WebApr 13, 2024 · Stars are the most basic building blocks of galaxies. The age, distribution, and composition of stars trace the history, dynamics, and evolution of their galaxy. Stars are responsible for the production and distribution of heavy elements, such as carbon, nitrogen, and oxygen. This artist's impression represents the early universe. Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. As the cloud … See more A star the size of our Sun requires about 50 million years to mature from the beginning of the collapse to adulthood.
