Astronomers identify a young heavyweight star in the Milky Way

22 August 2016 Astronomy Now

Researchers have identified a young star, located almost 11,000 light-years away, which could help us understand how the most massive stars in the universe are formed. This star, already more than 30 times the mass of our Sun, is still in the process of gathering material from its parent molecular cloud, and may be even more massive when it finally reaches adulthood.

In general, the larger a galaxy’s mass, the higher its rate of forming new stars. However, every now and then a galaxy will display a burst of newly-formed stars that shine brighter than the rest. Researchers using the Atacama Large Millimetre Array (ALMA) have found that galaxies forming stars at extreme rates 9 billion years ago were more efficient than average galaxies today.
