Scientists have observed the birth of a massive star within a dark cloud core about 10,000 light-years from Earth. The team used the new Atacama Large Millimeter/sub millimeter Array(ALMA) telescope to view the stellar womb which, at 500 times the mass of the Sun and many times more luminous, is the largest ever seen in our galaxy. ALMA is the most powerful radio telescope in the world.
The cloud is expected to form at least one star 100 times more massive than the Sun and up to a million times brighter. Only about one in 10,000 of all the stars in the Milky Way reach that kind of mass.
