NASA Astronomy Picture of the Day 22 February 2023: Sun trouble for Earth
The Sun's Solar cycle 25 commenced in 2019, and it is anticipated to reach its zenith in July 2025. This is the primary cause of the Sun's recent outbursts. Flares, prominences, sunspots, coronal mass ejections are the common harbingers of solar activity, as are plages and other related phenomena seen at other wavelengths. Unfortunately, the Earth is in for a challenging period. A G5-class solar storm, which is the horrendously powerful, striking the Earth can lead to the damage to satellites, interference in wireless communications like internet, mobile phone network and GPS, as well as power grid failures. Terrifyingly, it can even disrupt electronics such as pacemakers.
