Did you expect that gravitational waves would be discovered during your lifetime? Yes, and I thought it quite likely it would come from two colliding black holes of just the sort that we did see. I wr...
The measured fluxes of elementary particles multiplied by |R|2.7. The antiproton flux (red, left axis) is compared to the proton flux (blue, left axis), the electron flux (purple, right axis), and the...
Astronomers have found clear evidence of a planet orbiting the closest star to Earth, Proxima Centauri. The extrasolar planet is only slightly more massive than the Earth and orbits its star within th...
The largest 3D map of distant galaxies ever made has allowed one of the most precise measurements yet of dark energy, which is currently driving the accelerating expansion of the universe. The new mea...
With its very first observation, Japan’s Hitomi X-ray satellite has discovered that the gas in the Perseus cluster of galaxies is much less turbulent than expected. The unprecedented measurement...
The European Extremely Large Telescope (E-ELT) will be the largest optical/near-infrared telescope in the world, boasting a primary mirror 39 m in diameter. Its aim is to measure the properties o...
The origin of some of the heaviest chemical elements is due to rapid neutron capture, but the precise location where this cosmic alchemy takes place has been under debate for several decades. While co...
The High Energy Stereoscopic System (HESS) – an array of Cherenkov telescopes in Namibia – has detected gamma-ray emission from the central region of the Milky Way at energies never reache...
Since the start of its operations in 2004, the Auger Observatory has illuminated many of the open questions in cosmic-ray science. For example, it confirmed with high precision the suppression ...
Just a few months after its launch (CERN Courier November 2015 p11) and the successful completion of the on-orbit commissioning phase aboard the International Space Station, the CALorimetric Electron ...
