Scientists have found the trigger for making massive stars.
Astronomers know that the recipe for creating a star in a stellar nurseries includes hydrogen gas, dust and some amount of heat and gravity, but until now they did not know quite how all the parts come together or what triggers t...

Giant stars with planets often have smaller amounts of heavy elements than the Sun, say astronomers in the United States and Germany. This trend is surprising: it is opposite the one seen in planet-bearing main-sequence stars and suggests stars more massive than the Sun may give birth to planets in...
