CERN Large Hadron Collider detected above ground

This giant mural by American artist Josef Kristofoletti depicts the ATLAS particle detector at CERN. The mural, unveiled yesterday, is three stories tall yet still only one-third the size the actual detector, which gathers data on particle collisions in the Large Hadron Collider 100m directly underfoot.

The detector recently discovered evidence of elusive "excited" quarks, suggesting that quarks have even smaller constituent parts.
