NASA: Sun's Activity Rises, Stronger Storms Ahead!

9/19/2025

Summary

Story summary

A NASA study reveals the Sun is becoming more active after a two-decade decline, challenging previous forecasts of extended inactivity.
Since 2008, solar wind metrics have risen significantly, indicating a return to a more active phase.
This increase may lead to stronger solar storms, potentially disrupting power grids and communication systems.
The current solar cycle is expected to peak between 2025 and 2026, possibly causing intensified geomagnetic storms.
Historical trends show quiet periods often followed by heightened activity, though the underlying causes are still unclear.

History

Historical Context

The Carrington Event of 1859 was a powerful solar storm that disrupted telegraph systems across North America and Europe. Solar activity follows an 11-year cycle, with increased geomagnetic storms posing risks to modern technology. Since 2008, solar wind metrics have risen, highlighting the need for preparedness against potential disruptions to infrastructure from intensified solar storms.
