NASA and NOAA: The sun has reached the peak of the solar cycle and will continue to operate strongly for the next two years

NASA and NOAA forecasts indicate an increase in solar activity, increasing the risk of space weather and affecting satellites, communications and the aurora borealis

A cosmic mystery solved? New evidence shows that the planets influence the Sun's magnetic cycles.

Researchers identify eddy currents in the Sun, called Rossby waves, as mediating the tidal effects of Venus, Earth and Jupiter on the Sun's magnetic activity

NOAA satellites detected a strong solar storm

In late March 2024, NOAA satellites detected strong solar activity, including a powerful solar flare and coronal mass ejection (CME), which led to the strongest geomagnetic storm since 2017
