Gravitational waves crease and stretch the fabric of spacetime as they ripple out across the universe, potentially causing observable effects on beams in storage rings.
First results from the ANAIS experiment show no annual modulation, in conflict with longstanding results from the DAMA experiment.
High-energy X-rays reveal possible missing neutron star formed by the collapse of the famous supernova's progenitor star.
Recent studies suggest that plasma-wakefield acceleration also occurs naturally, potentially explaining the highest energy cosmic rays.
Observations of millisecond pulsars by the NANOGrav collaboration show early signs of consistency with gravitational waves with a period of decades.
Steven Weinberg has penned a concise account of the foundations of astrophysics of permanent value, writes our reviewer.
The Borexino collaboration has used an ingenious analysis to provide the first direct proof of the CNO cycle.
The excess could be due to a difficult-to-constrain tritium background, solar axions or solar neutrinos with a Majorana nature, says the collaboration.
HAWC and other high-altitude observatories are pushing the energy of gamma-ray observations into new territory to test fundamental symmetries.
The 2020s should see the start of a new type of astrophysics, reports Merlin Kole.
