It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'. The object is an unusual combination of an open cluster of stars, an emission nebula (the relatively dense, reddish-pink portion), a reflection nebula (the mainly NNE blue portion), and a dark nebula (the apparent 'gaps' in the former that cause the trifurcated appearance, also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers. The most massive star that has formed in this region is HD 164492A, an O7.5III star with a mass more than 20 times the mass of the Sun. This star is surrounded by a cluster of approximately 3100 young stars.\u003c\/p\u003e\n\u003cp\u003eBecause of the age of these posters, there are areas of wear and tear, particularly on the edges. I have done my best to take photos where they are torn or stained. The good news is that when framed, the tears press up well against glass, and edges can be hidden by mats. Any wear picked up from years are part of the vintage charm. \u003c\/p\u003e\n\u003cp\u003eThese posters are sent as unframed. They will be rolled up and delivered in a cardboard tube for protection.\u003c\/p\u003e\n\u003cp\u003eSee the FAQ section for more information on shipping, tracking and insurance.\u003c\/p\u003e","brand":"Lampposted","offers":[{"title":"Default Title","offer_id":57206273573251,"sku":"L3SCL","price":40.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/8538\/7139\/files\/il_fullxfull.4607997456_94y4.jpg?v=1768970933","url":"https:\/\/lampposted.com\/products\/1961-trifid-nebula-in-sagitterius-poster-27381","provider":"Lampposted","version":"1.0","type":"link"}
