An infrared dark cloud (IRDC) is a cold, dense region of a giant molecular cloud. They can be seen in silhouette against the bright diffuse mid-infrared emission from the galactic plane.〔http://web.ipac.caltech.edu/staff/carey/dark/dark.html 〕〔http://www.astro.ufl.edu/~jt/irext/ms.pdf〕 ==Discovery== Infrared dark clouds have only been recently discovered in 1996 using the ISO 〔http://www.mpia-hd.mpg.de/homes/stein/EPoS/Onlinematerial/fuller_irdcs.pdf.gz〕 and therefore are in need of further research.
