The search for the source of the cosmic particle shower hitting the Earth has led scientists to a decades-old astronomical cold case: the powerful and mysterious gamma-ray source, Geminga. Join us as we piece together the clues that finally unmasked the true identity of Geminga, and learn how this enigmatic object has confounded scientists for half a century.
