According to re-analysis of observational measurements, the star formation activity of typical, nearby galaxies is found to scale proportionally with the amount of gas present in these galaxies. This indicates that net gas supply from cosmic distances is the main driver of galactic star formation<\/a>.<\/p>\n Stars are born in dense clouds of molecular hydrogen gas that permeates the interstellar space of most galaxies. While the physics of star formation is complex, recent years have seen substantial progress towards understanding how stars form in a galactic environment.<\/p>\n While the gas mass of galaxies is regulated by a competition between gas inflows, outflows and consumption, the physics of the gas-to-star conversion is currently not well understood. Given its potentially critical role, many efforts have been undertaken to determine the gas depletion timescale observationally. However, these efforts resulted in conflicting findings partly because of the challenge in measuring gas masses reliably given current detection limits.<\/p>\n
