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.
SKAO director-general Philip Diamond describes how the world's largest radio telescope went from concept to construction.
The new analysis significantly improve the upper bound on the strength of gravitational waves produced during the epoch of inflation.
This week, at the 37th International Cosmic Ray Conference, space- and ground-based detectors unveiled new cosmic-ray anisotropy measurements from GeV to tens of EeV.
