The dynamic space environment that surrounds Earth – the space our astronauts and spacecraft travel through – can be rattled by huge solar eruptions
from the sun, which spew giant clouds of magnetic energy and plasma, a hot gas of electrically charged particles, out into space. The magnetic field
of these solar eruptions are difficult to predict and can interact with Earth’s magnetic fields, causing space weather effects.
A new tool called EEGGL – short for the Eruptive Event Generator (Gibson and Low) and pronounced “eagle" – helps map out the paths of these magnetically
structured clouds, called coronal mass ejections or CMEs, before they reach Earth. EEGGL is part of a much larger new model of the corona, the sun’s outer
atmosphere, and interplanetary space, developed by a team at the University of Michigan. Built to simulate solar storms, EEGGL helps NASA study how a CME
might travel through space to Earth and what magnetic configuration it will have when it arrives. The model is hosted by the Community Coordinated Modeling
Center, or CCMC, at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
