Key Points

This work provides a deeper understanding of the Sun's inner workings, crucial for predicting its activity and impact on Earth...

Indian astronomers have achieved a groundbreaking feat by mapping, for the first time, the variation in the Sun's rotation speed from its equator to its poles...

Using 100 years of daily solar observations from the Kodaikanal Solar Observatory, the team revealed new insights into the Suns chromospherea layer above the Sun's visible surface...

This differential rotation plays a key role in driving the Sun's magnetic activity, which can lead to phenomena like solar storms that affect Earth's technology...

To overcome this, researchers at the Indian Institute of Astrophysics (IIA) used solar plages and network features, which are bright regions in the chromosphere, to map the Suns rotation at higher latitudes.. . ) ..
