Why in news
Scientists led by Professor William J. Chaplin discovered a hidden signal beneath the Sun's surface by analyzing four decades of BiSON data, potentially redefining how solar cycles are measured.
Background
Findings indicate structural changes in Solar Cycles 22, 23, 24, and 25 are moving deeper into the outer layers of the solar core.
Facts for Prelims
- S&TBiSON: Birmingham Solar-Oscillations Network is a global network used to measure oscillations inside the Sun.
- FactThe study analyzed data spanning nearly four decades to identify structural changes in Solar Cycles 22 through 25.
- S&TTraditional solar activity gauging methods focus on sunspots and radio flux.
For Mains
Q. Discuss how advancements in helioseismology and solar oscillation monitoring are enhancing our ability to predict space weather and its impact on global infrastructure.
Dimensions to cover in your answer
- Predictive accuracy: Moving beyond sunspot observation to internal structural dynamics for better space weather forecasting
- Infrastructure vulnerability: Assessing the risk of solar flares on satellite communications and power grids
