Eagle Nebula with a representation of a giant molecular cloud

Shown here HST image of Eagle Nebula with part of its associated GMC. Since molecular hydrogen gas can only be observed by radio technique, contour lines are here used to show where the optically invisible hydrogen gas lies. The manner in which GMCs form stars may strongly depend on environment. In Milky Way, stars form slowly, soon disrupt and disperse molecular gas around them, as seen here in Eagle Nebula. In merging galaxies experiencing vast bursts of star formation, the fate of a GMCs may be quite different. As tenuous gas surrounding these clumps of dense molecular gas heast up, GMCs may get crunched and triggered into rapidly forming stars. The process may be so rapid that the new stars do not have time to disrupt the GMCs before nearly all the gas is used up. The result is that GMCs may turn into rich star clusters that evolve into globular clusters.
