The blue color typical of <A href="http://fusedweb.pppl.gov/CPEP/Chart_Pages/5.Plasmas/Nebula/Reflection.html">reflection nebula</A> is caused by blue light being <A href="http://hyperphysics.phy-astr.gsu.edu/hbase/atmos/blusky.html">more efficiently scattered</A> by the carbon <A href="http://antwrp.gsfc.nasa.gov/apod/ap980104.html">dust</A> than red light. The brightness of the nebula is determined by the size and density of the reflecting grains, and by the color and brightness of the neighboring star(s). <A href="http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1979ApJ...231..732J">NGC 1435</A>, <A href="http://www.cfht.hawaii.edu/HawaiianStarlight/AIOM/English/CFHT-Coelum-AIOM-Jun2007.html">pictured above</A>, surrounds <A href="http://www.seds.org/messier/more/m045_tab.html">Merope (23 Tau)</A>, one of the brightest stars in the <A href="http://antwrp.gsfc.nasa.gov/apod/ap060109.html">Pleiades</A> (M45).

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.
