Explanation: The Spitzer Space Telescope'sencompasing infrared view (http://www.spitzer.caltech.edu/Media/releases/ssc2008-11/index.shtml) ofthe plane of our Milky Way Galaxy is hard toappreciate (http://antwrp.gsfc.nasa.gov/apod/ap071020.html) in justone picture.In fact, more than 800,000 frames of data from Spitzer'scameras have now been pieced together in an<ahref="http://www.spitzer.caltech.edu/Media/releases/ssc2008-11/visuals.shtml">enormous mosaicof the galactic plane - themost detailed (http://www.spitzer.caltech.edu/Media/releases/ssc2008-11/moreinfo.shtml) infrared pictureof our galaxy ever made.The small portion seen here spans nearly 8 degrees, roughly theapparent (http://chandra.harvard.edu/photo/scale.html)width of your fist held at arms length, acrossthe galaxy's center (http://antwrp.gsfc.nasa.gov/apod/ap080104.html).The full mosaic is 120 degrees wide.Highlighted (http://www.spitzer.caltech.edu/Media/releases/ssc2008-11/release.shtml)in the false-color presentation are curving greenfilaments of light from complex molecules - polycyclic aromatichydrocarbons(PAHs (http://www.spitzer.caltech.edu/features/articles/20050627.shtml)) - that on Earth are the common, sootyproducts of incomplete combustion.The PAHs are found instarforming (http://www.ipac.caltech.edu/Outreach/Edu/sform.html) regions, along with reddish emissionfrom graphitedustparticles (http://www.chem.ucl.ac.uk/cosmicdust/specialist.htm#gas).Blue specks throughout the picture are individual Milky Way stars.
