Galaxies as 'cosmic cauldrons': Young stars heat molecular clouds and drive hot interstellar gas bubbles throughout galaxies

Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly 'inefficiently'. Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic systems, like 'cosmic cauldrons', consisting of components that constantly change their appearance. A team of scientists has reached these conclusions based on new observations of the NGC 300 spiral galaxy.
