Starless cloud cores reveal why some stars are bigger than others
December 20, 2013
Massive stars--those at least eight times the mass of the sun--present an intriguing mystery: How do they grow so large when the vast majority of stars in the Milky Way are considerably smaller? To find the answer, astronomers used the Atacama Large Millimeter/submillimeter Array telescope to look inside the cores of some of the darkest, coldest and densest clouds in the galaxy. What they found could explain starless cloud formation.
