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

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 ...

Is the Large Hadron Collider dangerous? No. Although powerful for an accelerator, the energy reached in the Large Hadron Collider (LHC) is modest by nature’s standards. Cosmic rays – particles ...

How is CERN is governed and organised? Find out about its Council, Member States and departments.

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: ...

In the 1860s, James Clerk Maxwell recognized the similarities between electricity and magnetism and developed his theory of a single electromagnetic force. A similar discovery came a century later, ...

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 ...

Katarzyna Dyga of IT department measuring the TETRA network coverage and quality of voice calls in the AD during the end of year technical stop 2017/2018 assuring that the TETRA service is reliable.

In 1928 the physicist Paul Dirac proposed that every particle of matter should have an antimatter counterpart. But shortly after the big bang, most of the antimatter disappeared, leaving behind the ...

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 ...

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 ...

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 ...
