Explanation: How do stars form? To better understand this complex and chaotic process, astronomers used the Hubble Space Telescope (http://www.stsci.edu/hst/HST_overview/) to image in unprecedented detail the star forming region LH 95 (http://en.wikipedia.org/wiki/LH_95) in the nearby Large Magellanic Cloud (http://antwrp.gsfc.nasa.gov/apod/ap060510.html) galaxy. Usually only the brightest, bluest, most massive stars in a star forming region (http://antwrp.gsfc.nasa.gov/apod/stellar_nurseries.html) are visible, but the above image (http://hubblesite.org/newscenter/archive/releases/2006/55/image/a/) was taken in such high resolution and in such specific colors that many recently formed stars that are more yellow, more dim, and less massive are also discernable. Also visible in the above scientifically colored image (http://heritage.stsci.edu/2006/55/caption.html) is a blue sheen of diffuse hydrogen gas (http://periodic.lanl.gov/elements/1.html) heated by the young stars, and dark dust (http://www.dtm.ciw.edu/lrn/psg_main.html) created by stars or during supernova explosion (http://www.youtube.com/watch?v=CWr8U7czifU)s. Studying the locations and abundances of lower mass stars (http://antwrp.gsfc.nasa.gov/apod/ap010604.html) in star forming regions and around molecular cloud (http://antwrp.gsfc.nasa.gov/apod/ap060409.html)s helps uncover what conditions were present when they formed. LH 95 (http://heritage.stsci.edu/2006/55/fast_facts.html) spans about 150 light years (http://chandra.harvard.edu/photo/cosmic_distance.html) and lies about 160,000 light years away toward the southern constellation (http://en.wikipedia.org/wiki/Constellation) of the Swordfish (Dorado).
