CERN, as it celebrated its 70th anniversary. To mark this major milestone, the Organization held a series of public events in ...

Two LHC magnets are seen before they are connected together. The blue cylinders contain the magnetic yoke and coil of the dipole magnets together with the liquid helium system required to cool the ...

Le LHC est l’accélérateur de particules le plus grand et le plus puissant du monde. C'est un anneau de 27 kilomètres de circonférence, formé de milliers d'aimants supraconducteurs et doté de ...

Dive into CERN's accelerator complex with these 360° panoramic photos. You can take a virtual tour of the installed machines and equipment, visit different areas of ...

As CERN's physics programme has evolved and expanded, physicists at the laboratory have used more powerful accelerators and detectors to study the fundamental particles. The laboratory has had to ...

The LHC will not generate black holes in the cosmological sense. However, some theories suggest that the formation of tiny 'quantum' black holes may be possible. The observation of such an event would ...

Accelerators at CERN boost particles to high energies before they are made to collide inside detectors. The detectors gather clues about the particles – including their speed, mass and charge – from ...

In 1929 the American astronomer Edwin Hubble discovered that the distances to far-away galaxies were proportional to their redshifts. Redshift occurs when a light source moves away from its observer: ...

CERN's cryogenic systems cool over 1000 magnets on the LHC to temperatures close to absolute zero, where matter takes on some unusual properties Cryogenics is the branch of physics that deals with the ...
