In 1925, Knut Lundmark published the paper "The motions and the distances of spiral nebulae". In here, he used the newly established distances to neighbouring galaxies to infer that a subgroup of novae, which he called "upper class novae" are fundamentally distinct from the others, being orders of magnitudes brighter. This insight can be seen to represent the birth of the field of supernova research - the "upper class novae" were later renamed "supernovae" by Baade and Zwicky in their 1934 paper, in which they also provided a first hypothesis for what these events could be.

For August 18-22 2025, we invite members of the global supernova research community to come to Stockholm to commemorate and celebrate 100 years of supernova science! We will look back at the milestone achievements over this first century of the field, review where we stand today in our understanding of supernovae, and discuss and exchange ideas on which paths to take in the years and decades ahead, both for theory, simulations, and observations.
The 5-day conference will be held in an integrated hotel and conference venue, located in the beautiful archipelago of Stockholm. We envision a vibrant week with about 100 participants.
