<B> Explanation: </B>
What creates the cosmic dust sculptures in the Rosette Nebula?  
Noted for the common beauty of its 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap010214.html">overall shape</A>, parts of the 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap020317.html">Rosette Nebula</A>, also known as NGC 2244, 
show beauty even when viewed up close.  
Visible above are 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap030816.html">globules</A> of dark 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap030706.html">dust</A> and gas that are slowly being 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap041004.html">eroded</A> away by the energetic light and winds by nearby massive stars.  
Left alone long enough, the 
<A href="http://antwrp.gsfc.nasa.gov/apod/ap030202.html">molecular-cloud globules</A> 
would likely form stars and planets.  
The <A href="http://www.astrogranada.org/astroimagen/html/pag_img/ccd/roseta_sii_oiii_ha.htm">above image</A> was taken in very specific colors of 
<A href="http://en.wikipedia.org/wiki/Sulfur">Sulfur</A> 
(shaded red), 
<A href="http://en.wikipedia.org/wiki/Hydrogen">Hydrogen</A> 
(green), and 
<A href="http://en.wikipedia.org/wiki/Oxygen">Oxygen</A> (blue).
The <A href="http://antwrp.gsfc.nasa.gov/apod/ap000111.html">Rosette Nebula</A> spans about 50 
<A href="http://chandra.harvard.edu/photo/cosmic_distance.html">light-years</A> 
across, lies 
<A href="http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2000A%26A...358..553H">about 4,500 light-years away</A>, 
and can be seen with a small telescope towards the <A href="http://www.astro.wisc.edu/~dolan/constellations/extra/constellations.html">constellation</A> of  the 
<A href="http://en.wikipedia.org/wiki/Unicorn">Unicorn</A> (<A href="http://www.astronomical.org/portal/modules/wfsection/article.php?articleid=55">Monoceros</A>).
