(PhysOrg.com) -- This image of the nebula NGC 3582, which was captured at ESO's La Silla Observatory in Chile, shows giant loops of gas bearing a striking resemblance to solar prominences. These loops are thought to have been ejected by dying stars, but new stars are also being born within this stellar nursery. These energetic youngsters emit intense ultraviolet radiation that makes the gas in the nebula glow, producing the fiery display shown here.

NGC 3582 is part of a large star-forming region in the Milky Way, called RCW 57. It lies close to the central plane of the Milky Way in the southern constellation of Carina (The Keel of Jason's ship, the Argo). John Herschel first saw this complex region of glowing gas and dark dust clouds in 1834, during his stay in South Africa.

This sequence starts with a wide-field view of the most spectacular parts of the southern Milky Way. As we zoom in we see the Southern Cross (Crux) and the famous Eta Carinae nebula. A little later we close in on the star-forming region NGC 3582, lying about 10 000 light-years from us in the constellation of Carina (The Keel). The final detailed view shows a new image of NGC 3582 and its surroundings from the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile. Credit: ESO/A. Fujii/Digitized Sky Survey 2.

Some of the stars forming in regions like NGC 3582 are much heavier than the Sun. These monster emit energy at prodigious rates and have very short lives that end in explosions as supernovae. The material ejected from these dramatic events creates bubbles in the surrounding gas and dust. This is the probable cause of the loops visible in this picture.

This image was taken through multiple filters. From the Wide Field Imager, data taken through a red filter are shown in green and red, and data taken through a filter that isolates the red glow characteristic of hydrogen are also shown in red. Additional from the are shown in blue.

The image was processed by ESO using the observational data identified by Joe DePasquale, from the United States, who participated in ESO's Hidden Treasures 2010 astrophotography competition. The competition was organised by ESO in October-November 2010, for everyone who enjoys making beautiful images of the using astronomical data obtained using professional telescopes.
