The nebula was probably known to ancient people as it is visible to the naked eye, the Maya had a folk tale which dealt with the region of the sky with Orion.<ref>Krupp, Edward C. “Igniting the Hearth.” Sky & Telescope (February 1999): 94.</ref> [[Ptolemy]] did include it in the ''Almagest'' (Great Book), [[Tycho Brahe]] also made note of the object in the late 16th century, and in 1603, [[Johann Bayer]] recorded it as '''Theta Orion''' in his ''Uranometria''. [[Galileo]] also looked towards the region the nebular is located and and detected several faint stars.  None of these astronomers though, realized there was a nebula.

The credit for discovering the nebula is given to '''Nicholas-Claude Fabri de Peiresc''' who in 1610 first recorded of a cloudy nebulosity in the [[Orion]] constellation.  [[Jesuit]] astronomer '''Johann Baptist Cysatus''' independently found the nebula in 1611 and published a note about it seven years later<ref name="history">http://messier.obspm.fr/Mdes/dm042.html</ref>.  It was independently rediscovered by [[Christiaan Huygens]] in 1656, who is often created for its discovery.  The designation M42 was given to the nebula by [[Charles Messier]], who recorded it in the first edition of his catalog of deep sky objects in 1774 (completed in 1771)<ref name="history">http://messier.obspm.fr/Mdes/dm042.html</ref>.  The nebula is also known as the first deep sky observation by [[William Herschel]] with his new self-constructed reflecting telescope in 1774<ref name="history">http://messier.obspm.fr/Mdes/dm042.html</ref>.

The gaseous nature of the Orion Nebula was identified in 1865 by [[William Huggins]] with the help of spectroscopy. On September 30, 1880, the Orion Nebula became the first nebula to have a successful photograph taken by it, by Henry Draper, who later obtained a second more detailed photograph of the Orion Nebula.  In 1993, the [[Hubble Space Telescope]] first looked to the Orion Nebula, and in 2005 recorded the most detailed imagery of the nebula yet, photographing over 3,000 stars contained within<ref>http://adsabs.harvard.edu/abs/2005AAS...20714601R</ref>.
