Sun's outer magnetic field mapped in 3D for the first time

AI Summary

Researchers have produced the first global three-dimensional estimates of the Sun’s magnetic field, including regions beyond its visible edge. The work could improve solar activity forecasts and help predict eruptions that may disrupt critical infrastructure on Earth.

A team of researchers has produced the first global, three-dimensional estimates of the sun's magnetic field, including the area beyond the sun's visible edge. This marks a step toward more accurate models of solar activity—and ultimately, better predictions of solar magnetic eruptions, which are the root cause of extreme space weather that can impact critical infrastructure technologies on Earth.
