They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

The speed at which science is changing our lives gives rise to tensions and concerns. In his talk at Leiden University, Minister Robbert Dijkgraaf (Education, Culture and Science) said we should talk more about science’s relationship with society and political decision-making.

How can we view societal challenges from a different perspective? At the EuroScience Open Forum (ESOF), Robert Zwijnenberg, Emeritus Professor of Art and Science Interactions, will call for more collaboration between artists and scientists.
