Dust Pillar of the Carina NebulaCredit:NASA,ESA,N. Smith(U. California, Berkeley)et al., and TheHubble Heritage Team(STScI/AURA)Explanation:Inside the head of this interstellar monster is a star that is slowly destroying it. The monster, actually an inanimate pillar ofgasanddust, measures over alight yearin length. The star, not itself visible through the opaque dust, is bursting out partly by ejectingenergetic beams of particles. Similar epic battles are being waged all over the star-formingCarina Nebula. The stars will win in the end, destroying theirpillars of creationover the next 100,000 years, and resulting in a newopen clusterof stars. The pink dots are newly formed stars that have already been freed from their birth monster. Theabove imageis only a small part of ahighly detailed panoramic mosaicof theCarina Nebulataken by theHubble Space Telescopeand released last week. The technical name for the stellar jets areHerbig-Haro objects. How a star createsHerbig-Haro jets is an ongoingtopic of research, but it likely involves anaccretion diskswirling around a central star. A second impressiveHerbig-Haro jetis visible across the bottom ofa larger image.Tomorrow's picture:venusian vortex<|Archive|Index|Search|Calendar|Glossary|Education|About APOD|Discuss|>Authors & editors:Robert Nemiroff(MTU) &Jerry Bonnell(USRA)NASA Official:Phillip NewmanSpecific rights apply.NASA Web Privacy Policy and Important NoticesA service of:ASDatNASA/GSFC&Michigan Tech.
