It’s true, we are all made of stardust. But which stars have to die to make it? All the complex elements needed for life – like carbon, oxygen and iron – are made by stars as they die. But stars die in several different ways, making different elements.
This talk will explain how the different death throes of stars create different elements for life. In the last few years, scientists have discovered that rare elements such as gold and silver are formed in the events where stellar corpses collide, showing that even dead stars can enrich the Universe.
All life on Earth is linked to the Universe and by looking to the stars we can understand where we came from and how we came to be.
