In 2012, the science world was celebrating big news that the Higgs boson particle has been found using CERN's Large Hadron Collider (LHC). For two years, the LHC was shut down so that important repair work can be done on it.

Now, after two years and the entire repair work, the LHC is all set to power up again for its second three-year run with an aim to unravel more of the universe's mysteries.

"With this new energy level, the LHC will open new horizons for physics and for future discoveries. I'm looking forward to seeing what nature has in store for us", said CERN Director General Rolf Heuer.

The LHC is the largest and most powerful particle accelerator in the world. Teams involved with the LHC have prepared the machine for running at almost double the energy of run 1. Heuer said that a lot of work has been done on the LHC over the last 18 months or so. And, now it is a new machine to make new discoveries.

During its repair work, the LHC has gone through major programme of maintenance and upgrading. Around 10,000 superconducting magnet interconnections were consolidated in order to prepare the LHC to run at its design energy.
