What is CREDO Science? Cosmic-Ray Extremely Distributed Observatory (CREDO) — Citizen Science collaborative project which enables a strategy for a global analysis of cosmic-ray data to reach the sensitivity to extremely extended cosmic-ray phenomena, we call them Cosmic-Ray Ensembles (CRE), invisible for individual detectors or observatories. So far, the cosmic-ray research has been oriented on detecting single air showers only, while the search for CRE is a scientific terra incognita. We aim at exploring this uncharted realm. Observation of CRE would have an impact on cosmology, fundamental particle interactions and ultra-high energy astrophysics. A large role in the CREDO project is the CREDO Detector mobile app, which uses the camera's matrix to register cosmic-ray particles. By creating a network of users around the globe, we get a cosmic-ray telescope the size of the whole Earth. All application code is public and available on our GitHub. CREDO is an open Citizen Science collaborative project and all collected data are public. In the project participate schools and institutions from 5 continents. If you think your school should join the program, contact us at contact@credo.science. If you have an idea and desire to implement it, you are welcome to join us!
