Title: 
The Rosette Nebula
Explanation: 
Would the Rosette Nebula [ http://www.seds.org/messier/xtra/ngc/n2244.html ] by any other name [ http://www.bartleby.com/100/138.28.22.html ] "look" as sweet [ ftp://ibiblio.org/pub/docs/books/gutenberg/etext00/0ws1610.txt ]? The bland New General Catalog [ http://www.ngcic.org/ ] designation of NGC 2237 [ http://nineplanets.org/twn/n2237x.html ] doesn't appear to diminish the appearance of the this [ http://robgendler.astrodigitals.com/ROSMOSLRGB.html ] flowery emission nebula [ http://antwrp.gsfc.nasa.gov/apod/emission_nebulae.html ]. Inside the nebula lies an open cluster [ http://antwrp.gsfc.nasa.gov/apod/open_clusters.html ] of bright young stars designated NGC 2244 [ http://antwrp.gsfc.nasa.gov/apod/ap000822.html ]. These stars formed about four million years ago [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1993ApJ...414..664K ] from the nebular material and their stellar winds [ http://www.bartol.udel.edu/~owocki/apsposter/sld001.htm ] are clearing a hole in the nebula's center, insulated by a layer of dust [ http://antwrp.gsfc.nasa.gov/apod/ap990509.html ] and hot gas. Ultraviolet light [ http://liftoff.msfc.nasa.gov/academy/universe/ultraviolet.html ] from the hot cluster stars causes the surrounding nebula to glow. The Rosette Nebula [ http://antwrp.gsfc.nasa.gov/apod/ap000111.html ] spans about 100 light-years [ http://einstein.stcloudstate.edu/Dome/constellns/lightyear.html ] across, lies about 5000 light-years away [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=2000A%26A...358..553H ], and can be seen with a small telescope towards the constellation [ http://www.astro.wisc.edu/~dolan/constellations/extra/constellations.html ] of Monoceros [ http://www.astronomical.org/constellations/mon.html ].
