Hubble Captures Spectacular "Landscape" in the Carina Nebula

NASA's Hubble Space Telescope captured this billowing cloud of cold interstellar gas and dust rising from a tempestuous stellar nursery located in the Carina Nebula, 7,500 light-years away in the southern constellation Carina. This pillar of dust and gas serves as an incubator for new stars and is teeming with new star-forming activity.
Hot, young stars erode and sculpt the clouds into this fantasy landscape by sending out thick stellar winds and scorching ultraviolet radiation. The low-density regions of the nebula are shredded while the denser parts resist erosion and remain as thick pillars. In the dark, cold interiors of these columns new stars continue to form.
In the process of star formation, a disk around the proto-star slowly accretes onto the star's surface. Part of the material is ejected along jets perpendicular to the accretion disk. The jets have speeds of several hundreds of miles per second. As these jets plow into the surround nebula, they create small, glowing patches of nebulosity, called Herbig-Haro (HH) objects.
Long streamers of gas can be seen shooting in opposite directions off the pedestal on the upper right-hand side of the image. Another pair of jets is visible in a peak near the top-center of the image. These jets (known as HH 901 and HH 902, respectively) are common signatures of the births of new stars.
This image celebrates the 20th anniversary of Hubble's launch and deployment into an orbit around Earth. Hubble's Wide Field Camera 3 observed the pillar on Feb. 1-2, 2010. The colors in this composite image correspond to the glow of oxygen (blue), hydrogen and nitrogen (green), and sulfur (red).

La nébuleuse de la Carène (ou Grande nébuleuse de la Carène, Nébuleuse d'Eta Carinae, NGC 3372) est une grande nébuleuse brillante qui englobe plusieurs amas ouverts d'étoiles. On y compte Eta Carinae et HD 9312A, deux des étoiles les plus massives et lumineuses de notre galaxie, la Voie lactée. La nébuleuse se situe à une distance estimée entre 6 500 et 10 000 années-lumière de la Terre. Elle fait partie de la constellation de la Carène. La nébuleuse comprend plusieurs étoiles de classe O.
Cette nébuleuse est l'une des plus grandes régions HII de la Voie lactée. Sa magnitude apparente est de 1,0.
Elle est également l'une des plus importantes nébuleuses diffuses observable. Bien que quatre fois plus grande et encore plus lumineuse que la nébuleuse d'Orion, la nébuleuse de la Carène est bien moins connue en raison de sa situation éloignée sur l'hémisphère sud. Elle fut découverte par Nicolas Louis de Lacaille en 1751-1752, depuis le cap de Bonne-Espérance.
