Look Up! December 2016 Royal Observatory Astronomers Radmila and Dhara take you through what to see in the night sky during the month of December in our family friendly Look Up! podcast. 

This month’s news story is all about how scientists worked out the origin of successive generations of stars in Globular clusters. The first and oldest stars in globular clusters contaminate the interstellar medium when they die and it’s from this contaminated medium that new and successive generations of stars are formed. Find out how scientists determined which stars are responsible for this contamination.
