The Taurus Molecular Cloud is a molecular cloud in the constellations Taurus and Auriga. This cloud hosts a stellar nursery containing hundreds of newly formed stars. The Taurus Molecular Cloud is only 140 pc (430 ly) away from earth, making it the nearest large star formation region. It also reveals characteristics that make it ideal for detailed physical studies. It has been important in star formation studies at all wavelengths. The cloud is notable for containing many complex molecules, including cyanopolyynes HC_nN for n=3,5,7,9. The dusty band seen in this section of the Taurus Molecular Cloud partially hides several newly born stars as well as the dense gas clouds on the verge of collapsing into new suns. This segment of the cloud spans about 10 light-years.
