Each solar cycle might seem like the same old story, but one thing has changed significantly since the previous solar maximum–our technology.
The magnetic record stored in rocks documents the liquid core’s behavior and possibly when the inner core formed. Whether it formed half a billion or more than a billion years ago, however, is up for debate.
The loss cone of energetic particles in the Earth’s inner magnetosphere is substantially modified during disturbed times, with important implications for the radiation-belt and ring current modeling.
Shock waves from Cold War era nuclear tests gave seismologists a glimpse of the inner core. Its wobbly rotation could explain phenomena such as the periodic change in the length of a day.
The experiment was one of the winning projects of the Astro Pi Challenge, in which hundreds of young scientists analyzed data collected from the International Space Station.
Unprecedented images of Mount Erebus’s inner workings show the unique trappings of a CO2-rich rift volcano.
A secondary suite of instruments on the Mars lander produced a first look at magnetic fields from the planet’s surface.
Five decades of data revealed a star undergoing a pause in magnetic activity similar to what the Sun experienced almost 400 years ago.
Through a local fixed time-step filter, global Holocene magnetic field models remain mathematically tractable refining our insight into field variability and improving archeological dating.
Nuevos experimentos en un antiguo sitio de derrames de petróleo en Minnesota sugieren que los procesos no biológicos por sí solos no pueden explicar la disminución de la magnetización.
