Nebulas

Many nebulae or stars form from thegravitational collapse of gas in theinterstellar medium or ISM. 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 opticalwavelengths. People think the supernova caused the Nebulas.
