Space Scientists Explain Physical Mechanisms of Sun Explosions

Oct 03, 2012

In a paper just published in Nature Physics, an international team of space scientists, including researcher Noé Lugaz in the Space Science Center of the UNH Institute for the Study of Earth, Oceans, and Space, explains the mysterious physical mechanisms underlying the origin of sun’s powerful coronal mass ejections (CMEs).

Geomagnetic storms caused by CMEs can disrupt power grids, satellites that operate global positioning systems and telecommunication networks, pose a threat to astronauts in outer space, lead to rerouting of flights over the polar regions, and cause spectacular auroras.

Their findings, based on state-of-the-art computer simulations, show the intricate connection between motions in the sun’s interior and these eruptions and could lead to better forecasting of hazardous space weather conditions.
