Sun's Internal Sound Waves Reveal Hidden Activity Patterns
TL;DR. Astronomers discovered a previously unknown pattern of solar magnetic activity in the Sun's shallow layer by analyzing 40 years of helioseismic data. - This internal "biorhythm" in the Sun indicates changes in solar activity not seen with traditional surface observations. - The new data analysis shows a gradual, long-term change in subsurface solar activity across multiple cycles. - The research was published in Monthly Notices of the Royal Astronomical Society, revealing deviations from predicted solar cycle behaviors.
- Astronomers analyzed 40 years of helioseismic data to study solar sound waves.
- A hidden pattern of magnetic activity in a shallow layer under the Sun's surface was identified.
- This internal 'biorhythm' helps explain deviations in recent solar cycles not observable from the surface.
- The study indicates a long-term change in the Sun's subsurface activity.
