Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment
Terra Nova, EarlyView.ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Geminids are initially cracked by atmospheric thermal stress
Astronomy & AstrophysicsContext. Geminids have the highest bulk density of all major meteor showers and their mechanical strength appears to depend on their mass. They are also the most active annual shower, enabling detailed studies of the dependence of their physical and ...

The Earth's Greatest Porous Media
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Meteoroid velocity distribution derived from head echo data collected at Arecibo during regular world day observations [PDF]
Atmospheric Chemistry and Physics, 2004 We report the observation and analysis of ionization flashes associated with the decay of meteoroids (so-called head echos) detected by the Arecibo 430 MHz radar during regular ionospheric observations in the spring and autumn equinoxes.

Physico-chemical properties of sporadic meteoroids inferred from de continuous monitoring of meteor and fireball activity [PDF]
, 2013 Sporadic meteoroids make up the bulk of the meteoroids striking the Earth. The combined action of gravitational and radiation forces have reduced the coherence of the initial orbits of these particles to such a degree that they have become so diffuse
