The Taurus molecular cloud 1 (often abbreviated TMC-1) is a molecular cloud embedded in the Taurus Molecular Cloud complex in the constellation of Taurus.
The cloud is notable for containing many complex molecules, including cyanopolyynes HCnN for n=3,5,7,9.
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.
