Scientists at NYU Abu Dhabi Detect Magnetic Waves Deep Within the Sun, Helping Predict Solar Activity

Researchers at NYU Abu Dhabi have discovered new large-scale waves moving deep inside the Sun, driven by magnetic fields far below the surface. These waves provide a window into parts of the Sun that are otherwise inaccessible, giving scientists a new tool to study how its magnetic field is formed and evolves over time.

The Sun’s interior is a dynamic ocean of hot, electrically charged gas shaped by rotation and magnetic forces. These magnetic fields drive the solar cycle, sunspots, and powerful eruptions that can disrupt satellites, communications, and power grids on Earth. Until now, the magnetic behavior deep inside the Sun was largely hidden from observation.

In the new study, published in Nature Astronomy, researchers at NYU Abu Dhabi’s Center for Astrophysics and Space Science analyzed more than a decade of the Sun’s natural vibrations. Their work revealed evidence for previously undetected, global-scale waves influenced by the Sun’s internal magnetism. By measuring how these waves move, the team can infer the strength and structure of magnetic fields far below the Sun’s surface.

“These waves give us a unique look at the Sun’s hidden magnetic system. Understanding these internal processes is crucial for predicting solar activity, which can impact satellites, communications, and power systems on Earth.”
