Since 2003, a LHC dipole magnet turned into a telescope has been following the Sun's movements from behind a concrete wall. This is the CAST experiment - hunting for hypothetical "axion" particles that could be produced in the centre of our star ☀️ Find out more about this experiment: https://home.cern/science/experiments/cast | CERN
