This ESO Picture of the Week shows a crescent-shaped cocoon of gas and dust a nebula known as NGC 3199, which lies 12 000 light-years away from Earth. It appears to plough through the star-studded sky like a ship through stormy seas. This imagery is very appropriate due to NGC 3199s location in Carina a southern constellation which is named after the keel of a ship! NGC 3199 was discovered by British astronomer John Herschel in 1834 as he compiled his famous catalogue of interesting night sky objects. The nebula has been the subject of numerous observations since, including those by ESOs 8.2-metre Very Large Telescope (eso0310, eso1117), and 2.6-metre VLT Survey Telescope (VST). The latter made the observations that comprise this image. The nebulas bright crescent feature is now known to be part of a much larger but fainter bubble of gas and dust. The nebula contains a notable star named HD 89358, which is an unusual type of extremely hot and massive star known as a Wolf-Rayet star. HD 89358 generates incredibly intense stellar winds and outflows that smash into and sweep up the surrounding material, contributing to NGC 3199s twisted and lopsided morphology. The VST, which began operations in 2011, can image a large area of sky at once an area twice the size of the full Moon with its 256-megapixel camera, OmegaCAM. This allows it to characterise interesting objects which its larger neighbour, ESOs Very Large Telescope, can then explore in even greater detail.
