Nebulae are bound together by the gravitational mass of their content, and often account for regions of star formation. Sometimes, under certain circumstances, nebulas form as a result of a single star supernova. Among the most beautiful cosmological objects in space, nebula can be found in a variety of spaces, colors, and sizes. Among the more well known nebula are the Pillars of Creation, the Crab Nebula, the Helix Nebula, the Horsehead Nebula, the Cat's Eye Nebula, and the Omega Nebula.
