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 credited 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 in 1774, using the new self-constructed reflecting telescope in 1774he'd recently completed<ref name="history">http://messier.obspm.fr/Mdes/dm042.html</ref>.
The Using [[spectroscopy]], 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 itbe successfully photographed, 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 images of the nebula yet, photographing over 3,000 stars contained within.<ref>http://adsabs.harvard.edu/abs/2005AAS...20714601R</ref>.
