Most of the gas is dispersed by stellar radiation, revealing galaxies to be highly dynamic systems, like &#8220;cosmic cauldrons,&#8221; consisting of components that constantly change their appearance. Based on new observations of the NGC 300 spiral galaxy, a team of scientists led by astrophysicist Dr. Diederik Kruijssen from Heidelberg University has now managed for the first time to reconstruct the time-evolution of molecular clouds and the star formation process within them. Their analysis shows that these clouds are short-lived structures undergoing rapid lifecycles, driven by the intense radiation from the new-born stars. The findings are published in Nature.&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\n Click here for original story, <a href=\"https:\/\/phys.org\/news\/2019-05-galaxies-cosmic-cauldrons.html\" target=\"_blank\" rel=\"nofollow noopener noreferrer\">Galaxies as &#8216;cosmic cauldrons&#8217;<\/a>&#013;<br \/>\n&#013;<br \/>\n&#013;<br \/>\nSource: Phys.org&#013;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Star formation within interstellar clouds of gas and dust, so-called molecular clouds, proceeds very rapidly yet highly inefficiently.
