A Turtle in Space? Planetary nebula [ http://antwrp.gsfc.…] NGC 6210 may look like a giant space turtle, but it is actually much more massive and violent. Fortunately, this gas cloud in Hercules [ http://www.astro.wi…] lies about 6500 light years away. NGC 6210 [ http://oposite.stsc…] was investigated [ http://presto.stsci…] with the Hubble Space Telescope [ http://antwrp.gsfc.…] because it showed evidence of unusual relative abundances of nebular gas. The resulting detailed representative-color picture, above [ http://oposite.stsc…], shows jets of hot gas streaming through holes in an older, cooler shell of gas. The central star that created the planetary nebula [ http://www.noao.edu…] is clearly visible in the center of the inset image. Analyses of data involving this recently released picture [ http://oposite.stsc…] may help explain the origin of chemical abundances [ http://adsabs.harva…] in this nebula and our Galaxy [ http://antwrp.gsfc.…].
