The Large Hadron Collider (LHC) is the world's largest and highest-energy particle accelerator .
It is expected to address some of the most fundamental questions of physics, advancing the understanding of the deepest laws of nature.
The LHC lies in a tunnel 27 kilometres (17 mi) in circumference, as deep as 175 metres (574 ft) beneath the Franco-Swiss border nearGeneva, Switzerland.
This synchrotron is designed to collide opposing particle beams of either protons at an energy of 7 teraelectronvolts (7 TeV or 1.12 microjoules) per nucleon, or lead nuclei at an energy of 574 TeV (92.0 µJ) per nucleus (2.76 TeV per nucleon).
The term hadron refers to particles composed of quarks. The Large Hadron Collider was built by the European Organization for Nuclear Research (CERN) with the intention of testing various predictions of high-energy physics,
including testing for the existence of the hypothesized Higgs boson and of the large family of new particles predicted by supersymmetry.
It was built in collaboration with over 10,000 scientists and engineers from over 100 countries, as well as hundreds of universities and laboratories.

The latest observations of a newly born star have found that it has a pair of spots on its surface that are heated to more than one million degrees. The presence of these spots, which are hot enough to produce X-ray radiation, confirms a theory for how stellar infants grow which Professor of Astronomy David Weintraub and his colleague Joel Kastner from Rochester Institute of Technology advanced several years ago.
During outbursts, the X-ray emissions of the infant star in McNeil's Nebula may brighten 100-fold. In this animation, magnetic fields drive powerful flows of dust and gas onto the star, creating two hot spots that produce the high-energy X-ray emissions. (NASA's Goddard Space Flight Center)
