Researchers demonstrate how a gas escapes ice at an extremely cold temperature, providing insight about how stars form in interstellar clouds. The mechanism by which hydrogen sulphide is released as gas in interstellar molecular clouds is described by scientists in Japan and Germany. Chemical desorption, is more efficient than previously believed, and this has implications for our understanding of star formation in molecular clouds.

Molecular clouds are rare, but are important parts of the galaxy where molecules form and evolve...
