- Indian astronomers have mapped the variation in the Sun's rotation speed from its equator to its poles for the first time.
- This was done by using 100 years of daily solar observations from the Kodaikanal Solar Observatory.
- This work provides a deeper understanding of the Sun's inner workings, crucial for predicting its activity and impact on Earth.
- The Sun experiences differential rotation, meaning different parts of it rotate at different speeds.
- The equator completes one full rotation in about 25 days, while the poles take about 35 days.
