A '''nebula''', from the [[Latin]] word for ''[[cloud]]'', is a cloud of interstellar [[dust]] and [[gas | gases]]. <ref>http://fusedweb.pppl.gov/CPEP/Chart_Pages/5.Plasmas/Nebula.html</ref>. Nebulae have been observed both within the [[Milky Way]] [[galaxy]] and in other galaxies. These large clouds of mostly hydrogen gas can form stars and planets. Secular scientists believe our solar system formed about 4.6 billion years ago from a nebula. <ref>http://www.windows.ucar.edu/tour/our_solar_system/formation.html</ref>

Some well-known nebulae are the [[Orion]] Nebula, the [[Crab]] Nebula, and the [[Horse]]-Head Nebula.

Nebulae often feature prominently in commercially available collections of deep-space images, since their colours and shapes are interesting, varied and curiously attractive.
