This cloud hosts a stellar nursery containing hundreds of newly formed stars.[2] 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.[3] The cloud is notable for containing many complex molecules, including cyanopolyynes HCnN for n=3,5,7,9.[4] {{multiple image| align = right | direction = horizontal | image1 = APEX Turns its Eye to Dark Clouds in Taurus (zoom).ogv | width1 = 300 | alt1 = | caption1 = This video begins with a wide-field view of the sky, before zooming into the Taurus Molecular Cloud region, about 450 light-years from Earth. Dark clouds of cosmic dust grains obscure the background stars at visible wavelengths. The submillimetre-wavelength observations from the LABOCA camera on APEX reveal the heat glow of the dust grains, shown here in orange tones. The observations cover two regions in the cloud, which are known as Barnard 211 and Barnard 213. In them, newborn stars are hidden, and dense clouds of gas are on the verge of collapsing to form yet more stars. | image2 = APEX Turns its Eye to Dark Clouds in Taurus (pan).ogv | width2 = 300 | alt2 = | caption2 = This video pans over part of the Taurus Molecular Cloud region. }}{{-}} References1. ^1 2 3 {{cite web |url= http://simbad.u-strasbg.fr/simbad/sim-id?submit=display&bibdisplay=refsum&bibyear1=1850&bibyear2=%24currentYear&Ident=%40732625&Name=TMC-1#lab_bib |title= TMC-1 -- Molecular Cloud |publisher= SIMBAD |accessdate= 2014-03-14 }} {{Sky|04|41|00|+|25|52|00|430}}{{nebula-stub}}2. ^{{cite journal|last1=Luhman|first1=K.
