Solar Activity Unexpectedly Rises After Decades of Decline, NASA Reports
Washington D.C. – In a surprising turn of events, the sun is showing increased activity after a decades-long period of decline, according to new research from the United States’ National Aeronautics and Space Governance (NASA). The findings, published September 8, 2025, in Astrophysical Journal Letters, reveal a resurgence in key indicators of solar activity – sunspots, radiation bursts (flares), and coronal mass ejections (CMEs).
For years, scientists predicted the sun would enter a prolonged period of low activity. Observations since the 1980s showed a consistent downward trend in each 11-year solar cycle, with fewer sunspots, flares, and CMEs than the cycle before. In fact, 2008 marked the lowest recorded level of solar activity in history, leading researchers to believe a new era of solar quiescence had begun.
“All indicators previously estimated that the sun would enter a long-term low activity phase,” explains Jamey Jasinski, lead author of the study and a physicist specializing in outer plasma at NASA’s Jet propulsion Laboratory. “Therefore,this change was really surprising. The sun was slowly active again.”
This unexpected shift is prompting further examination into the dynamics of our star. While the implications of increased solar activity are still being studied, it’s crucial to understand the potential impact on both Earth and ongoing space missions.
The rise in solar activity is a meaningful progress, and World-Today-News.com will continue to follow this story as it unfolds.
