All Earthly matterwas once born in the nuclearfurnace of an ancient star. How do chemicals that were once part of this stellar factory disperse into space and eventually turn into the molecules of life after a star's violent death?

Sue Nelson talks to Helen Fraser from Leiden University in the Netherlands, who is part of a team using new techniques to look into the void of space to find the birth of stars, planets and life itself.
