giant molecular cloud

(GMC)
(interstellar gas cloud with molecules, thousands of solar masses)

A giant molecular cloud (GMC) is a molecular cloud (i.e., including compounds such as molecular hydrogen (aka HH or H2), with a mass on the order of 103 to 107 solar masses. They are assumed to be a common place for star formation, pretty much necessary. Bound GMCs (gravitationally bound) are observed, but most appear to be unbound. An area of research is how gravitationally bound volumes that become stars manage to form within an unbound GMC.
