Locating Moonquakes With Single‐Station Seismology

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Renewed international interest in lunar seismometer deployments requires robust single‐station location approach for the highly scattering Moon's crust. We present an event‐location strategy using major lunar event types recorded by the Apollo seismic network. Frequency‐dependent polarization analysis provides P‐wave back‐azimuth and incidence,

Reanalysis of SKR Source Crossed by Cassini: Loss Cone Electrons as a Secondary Source of Free Energy

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Saturn's Kilometric Radiation (SKR) is a powerful non‐thermal radio auroral emission produced by the Cyclotron Maser Instability (CMI), which generates waves close to the local cyclotron frequency in a highly magnetized plasma from mildly relativistic electrons.

Updated Interior Structure of Callisto From a Reanalysis of Galileo Data

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract The internal structure of Callisto has been a long‐standing question since the Galileo mission. Previous analyses suggested a largely undifferentiated interior. We present an updated interior structure for Callisto derived from a reanalysis of Galileo's Doppler tracking data using new signal processing techniques.

Detecting an Ocean Inside Callisto With Geodetic Measurements From Europa Clipper and Juice

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Determining whether Callisto hosts a subsurface ocean, and the implications for material and energy transport through its hydrosphere, is of high interest to NASA's Europa Clipper and ESA's Juice missions. A recent reanalysis of Galileo magnetometer data strengthens the ocean hypothesis, but definitive confirmation awaits new measurements.

Has Kronos Devoured Planet Nine and Its Epigones?

Universe
The Planet Nine hypothesis encompasses a body of about 5–8 Earth’s masses whose orbital plane would be inclined to the ecliptic by one or two tens of degrees and whose perihelion distance would be as large as about 240–385 astronomical units. Recently, a
