The Nature of Gas Clouds in Space
Giant gas clouds and nebulae exist in space due to the interplay of various forces, including gravity. Although gas tends to disperse in a vacuum, in space, low temperatures and gravity allow some gas particles to come together to form these clouds. The turbulence within these clouds creates unique and beautiful shapes, as seen in images of the Orion Nebula. This turbulence and the competing energies in space contribute to the diverse formations of stars and planets from these gas clouds.
