5/17/2023 0 Comments Carina nebula 4kHubble's Wide Field Camera 3 observed the pillar on Feb. This image celebrates the 20th anniversary of Hubble's launch and deployment into an orbit around Earth. These jets (known as HH 901 and HH 902, respectively) are common signatures of the births of new stars. Another pair of jets is visible in a peak near the top-center of the image. Long streamers of gas can be seen shooting in opposite directions off the pedestal on the upper right-hand side of the image. As these jets plow into the surround nebula, they create small, glowing patches of nebulosity, called Herbig-Haro (HH) objects. The jets have speeds of several hundreds of miles per second. Part of the material is ejected along jets perpendicular to the accretion disk. In the process of star formation, a disk around the proto-star slowly accretes onto the star's surface. In the dark, cold interiors of these columns new stars continue to form. The low-density regions of the nebula are shredded while the denser parts resist erosion and remain as thick pillars. Hot, young stars erode and sculpt the clouds into this fantasy landscape by sending out thick stellar winds and scorching ultraviolet radiation. This pillar of dust and gas serves as an incubator for new stars and is teeming with new star-forming activity. 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.
