Nebula

A nebula (pl. nebulae or nebulas) or cloud is a glowing section of the interstellar medium, containing ionized, neutral, or molecular hydrogen as well as cosmic dust. These are created when star explodes and blows its mass outward in a massive supernova, or are left over from the Age of Creation. Nebulae frequently serve as areas where stars are born. Within these regions, gas, dust, and other substances come together to create denser patches, attracting additional matter until they become dense enough to give rise to stars. The leftover material is believed to contribute to the formation of planets and other objects within planetary systems.
