The sun is becoming more active and may reach peak activity sooner than expected. We're currently approaching solar maximum, when the sun reaches peak activity, which experts have previously predicted should happen in 2025. NASAFor example, already this year a powerful solar flare caused widespread radio blackouts that disrupted high-frequency radio signals in North America, Central America, and South America. In the past, powerful solar storms have surged the Quebec power grid, causing blackouts that lasted up to eight hours. Why experts think solar maximum will hit soonWhen the sun's magnetic field is weak, its surface gets a lot more interesting to look at.
