NASA image release April 22, 2010
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).
