Gamma-ray measurements by H.E.S.S. provide a new way to test models of the origin of cosmic rays.
Studies of proton-gas collisions at the LHC enable a deeper understanding of the antiproton flux in cosmic rays.
Physicists gathered to discuss machine-learning methods applied to detect signals from gravitational-waves.
With telescopes at the South Pole and in the Chilean Atacama Desert, the newly endorsed CMB-S4 observatory will exceed the capabilities of earlier experiments by more than an order of magnitude.
Despite it being our galactic home, many open questions remain about the origin and evolution of the Milky Way.
In addition to studying galaxy formation, the James Webb Space Telescope will deepen our understanding of dark matter and dark energy.
Theorists and experimentalists met at CERN in October to discuss new detector concepts and theoretical approaches to search for a cosmological gravitational-wave background.
Precise measurements of solar neutrinos have enabled the Borexino experiment to definitively observe the two main fusion reactions in stars.
September workshop targeted a roadmap for extraterrestrial cold-atom experiments to probe the foundations of physics.
The diffuse photon background that fills the universe does not limit itself to the attention-hogging cosmic microwave background.
