**Bangalore, India (November 5, 2024):** Scientists continue to be baffled by the Sun’s unique rotation. While our Earth completes a rotation in a single day, the Sun exhibits a phenomenon known as “differential rotation,” meaning different parts rotate at different speeds.
The Sun’s equator spins fastest, completing a rotation in 26.5 days, while regions at the poles take a full 31.1 days. This variation in rotation period is still not fully understood by solar physicists.
Daily photographs of the Sun’s surface are analyzed to track the movement of sunspots, filaments, and plages across its surface. This data is then used to calculate the sidereal rotation period, the time it takes for a celestial body to complete one full rotation relative to the stars.
The Sun’s extreme temperatures, reaching 15 million degrees Kelvin in its core and 6,000 degrees Kelvin on its surface, contribute to its gaseous state, known as plasma. Despite these extreme conditions, the precise reason behind its differential rotation remains a mystery.
