- NASA and the National Oceanic and Atmospheric Administration (NOAA) has announced the commencement of solar cycle 25.
- The solar minimum for Solar Cycle 25 occurred in December 2019.
- This solar cycle will be as strong as the last solar cycle, which was a “below-average cycle” but not without risks.
- Like seasons on Earth, the Sun follows a cycle of 11 years, during which solar activities fluctuate between solar minimum and maximum.
- So far, astronomers have documented 24 such cycles, the last one ended in 2019.
- Solar eruptions can cause lights in the sky, called aurora, or impact radio communications.
- Extreme eruptions can even affect electricity grids on Earth.
