Editing Dust (section)

==Outer space==
[[Cosmic dust]] is widely present in [[outer space]], where gas and dust clouds are the primary precursors for [[planetary system]]s. The [[zodiacal light]], as seen in a dark night sky, is produced by [[sunlight]] reflected from particles of dust in orbit around the [[Sun]]. The tails of [[comet]]s are produced by emissions of dust and ionized gas from the body of the comet. Dust also covers solid planetary bodies, and vast [[dust storm]]s can occur on [[Mars]] which cover almost the entire planet. Interstellar dust is found between the [[star]]s, and high concentrations produce [[Nebula|diffuse nebulae]] and [[reflection nebula]]e.

Dust is widely present in the [[galaxy]]. Ambient [[radiation]] heats dust and re-emits radiation into the [[microwave]] band, which may distort the [[cosmic microwave background]] power spectrum. Dust in this regime has a complicated [[emission spectrum]] and includes both thermal dust emission and [[spinning dust]] emission.<ref>{{cite journal|author=P.

Dust samples returned from outer space have provided information about conditions of the early [[Solar System|solar system]]. Several [[spacecraft]] have sought to gather samples of dust and other materials. Among these craft was [[Stardust (spacecraft)|''Stardust'']], which flew past [[81P/Wild]] in 2004, and returned a capsule of the comet's remains to Earth.<ref>{{Cite book |last=Hanslmeier |first=Arnold |url=https://books.google.com/books?id=jmriAwAAQBAJ&pg=PA104 |title=Astrobiology The Search for Life in the Universe |date=2013-01-02 |publisher=Bentham Science Publishers |isbn=978-1-60805-473-2 |pages=104 |language=en |access-date=2022-12-24 |archive-date=2022-12-24 |archive-url=https://web.archive.org/web/20221224031239/https://books.google.com/books?id=jmriAwAAQBAJ&pg=PA104 |url-status=live }}</ref> In 2010 the Japanese ''[[Hayabusa]]'' spacecraft returned samples of dust from the surface of an [[asteroid]].<ref>{{Cite book |last=Ridpath |first=Ian |url=https://books.google.com/books?id=VmZaDwAAQBAJ&pg=PT497 |title=A Dictionary of Astronomy |date=2018-04-26 |publisher=Oxford University Press |isbn=978-0-19-254261-8 |pages=497 |language=en |access-date=2022-12-24 |archive-date=2022-12-24 |archive-url=https://web.archive.org/web/20221224031238/https://books.google.com/books?id=VmZaDwAAQBAJ&pg=PT497 |url-status=live }}</ref>
