Exciting times for the #astrophysics community, as evidence of a new class of #GravitationalWaves is revealed. Scientists suggest they are caused by pairs of supermassive black holes merging and generating ripples in space-time. explains. 👇

⚠ Breaking News ⚠ An international team of astronomers has found evidence of a new class of gravitational waves. 🤯 Learn more ▶ epta.eu.org Check out our current understanding of gravitational waves in the graphic below 👇
A graphic showing our current understanding of gravitational waves. Broken into two sections, it explains the role of gravitational wave observatories (an unusual type of telescope), and our current understanding of the gravitational wave spectrum. Gravitational waves allow us to get an unobscured view of the universe, depending on the instrument used, right back to very first moments of the universe.

Today’s #ThrowbackThursday takes us to the control room of the muon g-2 experiment, back in 1975, in the South-East hall of the Super Proton Synchrotron (SPS). The experiment aimed to test quantum electrodynamics.

Here we see the testing of a novel hexagonal silicon sensor for the CMS High-Granularity Calorimeter. In order for the #HiLumiLHC to run smoothly, both CERN’s flagship accelerator and its experiments need to be upgraded to support the higher collision rate and levels of… Show more

After #restartingLHC in April 2022, CERN's engineers have been hard at work in preparation for #LHCRun3 and collisions at the highest-ever energy of 13.6 TeV. Curious about what they have been doing? Delphine Jacquet, one of the Engineers in Charge (EiC) at the #LHC, explains.

Bouncing reflections, what could it be? 🤔 This #ThrowbackThursday we go back to 1975, where a plexiglass surface is being polished to serve as a mirror in a Cherenkov counter. The arm coming in from the top left carries the polishing disc, which is impregnated with a special… Show more

Today’s photo of the week brings us to the… Esplanade des Particules This blue-coloured public space where the flags of CERN’s Member States stand, was inaugurated back in 2018 to welcome visitors and the general public. It became CERN’s official address ever since. It… Show more
Landscape image of a blue pavement with multiple flags of CERN member states and a road crossing through the center. A sphere-shaped building made out of timber and surrounded by trees is on the left side of the road. A long white building, behind the flags, is at the end of the road.

Connecting the small and the large scales 🔭 Gravitational waves have made their mark on a decade of extraordinary discoveries in physics. But current gravitational-wave observatories cover just a narrow spectrum of the whole range of wavelengths that are emitted. Future… Show more
