Photographer's Note

CMS detector is one of the four particle physics experiment of the "new" (already in service since last year) particle accelerator (LHC) built at CERN near Geneva.
In this accelerator, a 27km ring burried 100m underground, two protons beams (elementary particles) circulating in opposite direction are accelerated to almost the speed of the light and are brought to collision just in the middle of these detectors.
The detector is like a huge camera, it takes a sort of picture of collisons. These pictures (rather a huge amount of data...) are then analysed and decrypted by physicist who aim to better understand the origins of our universe and the physics laws that govern it.
CMS is a monster of 16m diameter and 25m length made of 12500t of steel, silicon, crystals, brass, cables and electronics.
This picture was taken during its construction in 2007.

PS : I know it's not really earth (we are 100m underground...) but as it's almost a camera, i thought i could share this picture here.
