The Sun, the energy engine of our planetary system, has shown a surge in activity since 2008. This change surprised the scientific community, which had expected a prolonged period of calm.
According to NASA, the phenomenon marks the end of more than three decades of solar decline and raises questions about the impact on Earth and modern technology.
The Sun "wakes up slowly"
The study, led by Jamie Jasinski from Jet Propulsion Laboratory and published in Astrophysical Journal Letters, revealed that the Sun is "waking up slowly".
Observation systems have detected an increase in plasma explosions and magnetic fields since 2008.
The solar cycle and the end of calm
The Sun operates in 11-year cycles. We are currently in Solar Cycle 25, which began in 2020. The previous one was the weakest in a century, which led to the idea of a "deep solar minimum".
