Image Description and Details :

One of the first images taken after NASA astronauts repaired the Hubble Space Telescope in December 1999, was NGC 1999, a nebula in the constellation Orion. While the Hubble image was much deeper than the image presented here, it nevertheless generated a lot of interest amongst astronomers. NGC 1999 is an example of a reflection nebula. Like fog around a street lamp, a reflection nebula shines only because the light from an embedded source illuminates its dust; the nebula does not emit any visible light of its own. NGC 1999 lies close to the famous Orion Nebula, about 1,500 light-years from Earth, in a region of our Milky Way galaxy where new stars are being formed actively. NGC 1999 was discovered some two centuries ago by Sir William Herschel and his sister Caroline, and was catalogued later in the 19th century as object 1999 in the New General Catalogue.Total Integration 24h40mLum 14x20m=4h40mRed 14x20m=4h40mGreen 14x20m=4h40mBlue 17x20m =5h40mHa = 10x30m=5h00m

Reflection nebula NGC 1999 in Orion. The small bluish patch of nebulosity with an inverted T at its center is enveloped within a much larger area of emission nebulosity in Orion. The nebula is illuminated by the variable star V380 Orionis which is visible right nest to the dark inverted T. This dark are is a source of much discussion and has been images by many of the great observatories.
