<B> Explanation: </B>
The bright clusters and nebulae of planet Earth's night sky are often
<A href="http://antwrp.gsfc.nasa.gov/apod/ap010205.html">named</A> for
<A href="http://antwrp.gsfc.nasa.gov/apod/ap011214.html">flowers</A> or
<A href="http://insects.org/">insects</A>, and
<A href="http://antwrp.gsfc.nasa.gov/apod/ap980602.html">NGC 6302</A> is no exception.
With an estimated surface temperature of about 250,000 degrees C,
the central star of this particular
<A href="http://antwrp.gsfc.nasa.gov/apod/ap040207.html">planetary</A> nebula is exceptionally
hot though -- shining brightly in ultraviolet light but hidden from
direct view by a dense torus of dust.
Above is a
<A href="http://internal.hubblesite.org/newscenter/archive/releases/2009/25/image/b/">dramatically detailed close-up</A> of the
<A href="http://www.aao.gov.au/images/captions/aat011.html">dying
star's nebula</A> recorded by the 
<A href="http://www.nasa.gov/mission_pages/hubble/multimedia/ero/index.html">newly upgraded Hubble Space Telescope</A>.
Cutting across a bright cavity of ionized gas,
the dust torus surrounding the central star is in the upper
right corner of this view, nearly edge-on to the line-of-sight.
Molecular hydrogen 
<A href="http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2005hris.conf..423M">has recently been detected</A> in this hot star's dusty cosmic shroud.
<A href="http://adsabs.harvard.edu/abs/2008MNRAS.385..269M">NGC 6302</A> lies about 4,000 light-years away in the
<A href="http://www.arachnology.org/Arachnology/
Arachnology.html">arachnologically</A> correct constellation
<A href="http://hawastsoc.org/deepsky/sco/index.html">Scorpius</A>.
