Page 3: Research news on space weather

Space weather refers to the time-varying conditions in near-Earth space and throughout the heliosphere driven primarily by solar activity, including the solar wind, coronal mass ejections (CMEs), solar flares, and variations in the interplanetary magnetic field. As a physical phenomenon, it encompasses the coupling of solar outputs with Earth’s magnetosphere, ionosphere, and thermosphere, producing geomagnetic storms, substorms, ionospheric disturbances, and energetic particle events. These processes are governed by magnetohydrodynamic and plasma-physical interactions, including magnetic reconnection, wave–particle interactions, and particle acceleration, and are quantitatively characterized using indices such as Kp, Dst, AE, and measures of solar wind and IMF parameters.

Simulating solar storms for satellite operator training

Threats from space aren't always obvious, but statistically, it's only a matter of time before one of them happens. One of the most concerning for many space experts is a massive solar storm, like the one that literally lit ...

New 3D model reveals geophysical structures beneath Britain

Magnetotelluric (MT) data, which contain measurements of electric and magnetic field variations at Earth's surface, provide insights into the electrical resistivity of Earth's crust and upper mantle. Changes in resistivity, ...

NASA launches mission to study sun-fueled solar bubble

A NASA mission to study the heliosphere—the sun's magnetic bubble that shields our solar system—and develop a better understanding of space weather was launched from the agency's Kennedy Space Center along Florida's Atlantic ...

New NASA mission to reveal Earth's invisible 'halo'

A new NASA mission will capture images of Earth's invisible "halo," the faint light given off by our planet's outermost atmospheric layer, the exosphere, as it morphs and changes in response to the sun. Understanding the ...
