UD physics professor (and DE Space Grant Associate Director) Spencer Axani has invented a portable, low-cost detector that senses invisible particles from space called muons. Muons help scientists learn more about some of the most extreme phenomena in the universe, like exploding stars, gamma ray bursts and blazars. CosmicWatch is being used in international astrophysics experiments, and in high school and college classrooms across the country, introducing a new generation of scientists to the field of particle physics.
