The Large Hadron Collider (LHC) is set to shut down for two years to allow technicians to make repairs for future use.
The move comes after CERN scientists completed the last batch of experiments on the LHC, after a year in which the multi-billion euro particle accelerator revealed what Geneva scientists believe to be the Higgs Boson. The so-called "God particle" helps to explain how particles obtain their mass.
The LHC will be operational once again in 2015, with scientists looking to discover new explanations into the workings of the universe.
The highly reported discovery of the Higgs Boson in 2012 is just the beginning of the accelerator's life, according to Pippa Wells, a physicist who works on the LHC.
"The headline discovery was just the start," said Wells. "We need to make more precise measurements, to refine the particle's mass and understand better how it is produced, and the ways it decays into other particles."
