Many nebulae or stars form from the gravitational collapse of gas in the interstellar medium . As the material collapses under its own weight, massive stars may form in the center, and their ultraviolet radiation ionizes the surrounding gas, making it visible at optical wavelengths. The formed stars are sometimes known as a young, loose cluster. Every soul on this planet, kept alive by a star, shines by his own light. Each light has a story, a vibration. This set of lights and vibrations is 'B.SOUL'.
