New Observations of Cosmic Noise Absorption in the South American Magnetic Anomaly (SAMA) Using a Next‐Generation Riometer

open access: yesSpace Weather, Volume 24, Issue 7, July 2026.
Abstract This study reports the first observations of cosmic noise power (CNP) and cosmic noise absorption (CNA) obtained with a next‐generation riometer installed at the Southern Space Observatory (SSO/INPE) in Brazil, located within the South American Magnetic Anomaly (SAMA).

New Terrestrial Native Iron Discovered on Earth's Surface

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Native iron is a major common mineral in lunar samples and meteorites but rarely occurs on Earth's surface, as its stability requires highly reducing conditions with very low oxygen fugacity. To date, native iron has mainly been found in basalts, ophiolites, and deep hydrothermal systems.

Galactic centre gamma-rays from trapped cosmic rays [PDF]

open access: yes, 1977
The emissivity of Galactic-Center (GC) gamma-rays with energies greater than 100 MeV is calculated by assuming that primary cosmic-ray nuclei lose all their energy before escaping from the Galaxy.

How the 29 July 2025 M8.8 Kamchatka Earthquake Shook the Ionosphere Over Japan

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 7, July 2026.
Abstract This study investigates the mid‐field (∼1,100–3,800 km) ionospheric response to the 29 July 2025 Kamchatka earthquake over Japan using multi‐instrument observations, raytracing, and numerical simulations. Total electron content (TEC) observations from GPS satellite G04 and Galileo satellite E10 show a maximum TEC perturbation of ∼0.5–0.85 TECU

The Dipole Anisotropy of Galactic Cosmic Rays [PDF]

open access: yes, 2019
The arrival directions of Galactic cosmic rays exhibit anisotropies up to the level of one per-mille over various angular scales. Recent observations of TeV-PeV cosmic rays show that the dipole anisotropy has a strong energy dependence with a phase-flip ...
