Probing the Milky Way’s violent history

Data collected by the Hubble and Green Bank telescopes bring a fresh perspective on the origin of the galaxy's enormous "Fermi bubbles".

Webb opens new era in observational astrophysics

The keenly awaited first science-grade images from the James Webb Space Telescope did not disappoint.

Counting down to LISA

Stefano Vitale describes the status of LISA as the space-based gravitational-wave observatory moves into its final design phase.

Accretion disk around magnetar 4U 0142+61

X-ray polarisation probes extreme physics

IXPE’s first results provide novel insights into the properties of neutron stars.

Flying high with silicon photomultipliers

Silicon photomultipliers offer many advantages over traditional tube devices, but further R&D is needed to understand their performance under radiation damage.

Thermonuclear explosions fuel cosmic rays

Gamma-ray measurements by H.E.S.S. provide a new way to test models of the origin of cosmic rays.

LHCb constrains cosmic antimatter production

Studies of proton-gas collisions at the LHC enable a deeper understanding of the antiproton flux in cosmic rays.

Gravitational-wave astronomy turns to AI

Physicists gathered to discuss machine-learning methods applied to detect signals from gravitational-waves.

Exploring the CMB like never before

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.
