The Extremely Large Telescope has passed its construction mid-point atop Cerro Armazones in the Atacama Desert.

Time dilation finally observed in quasars

Data from the Sloan Digital Sky Survey and PanSTARRS-1 resolve one of the main problems with the standard cosmological model.

Gravitational waves: a golden era

Azadeh Maleknejad and Fabrizio Rompineve explain why precision measurements of the gravitational-wave spectrum are essential to explore particle physics beyond the reach of colliders.

Hints of low-frequency gravitational waves found

Pulsar timing arrays have spotted the first evidence for a stochastic gravitational-wave background.

Joined-up thinking in vacuum science

CERN is home to an international effort to develop the next generation of gravitational-wave telescopes.

A soft spot for heavy metal

Together with colleagues from CERN’s Vacuum, Surfaces and Coatings and Mechanical and Materials Engineering groups, Audrey Vichard is working on R&D for the Einstein Telescope.

DAMPE confirms cosmic-ray complexity

The space-based Chinese–European Dark Matter Particle Explorer (DAMPE) reports detailed insights into the various spectral "breaks" in cosmic-ray spectra.

CERN shares beampipe know-how for gravitational-wave observatories

Participants of a recent CERN workshop discussed vacuum technologies for next-generation gravitational-wave observatories such as the Einstein Telescope.
