Powerful "Cannibal Storm" Threatens Earth's Tech, Auroras Possible
13 Nov
Summary
- Largest solar storm in over 20 years
- Disruptions to communications and satellite navigation
- Nasa postpones Mars mission launch

On November 13, 2025, a powerful solar storm is poised to wreak havoc on Earth's technology and communications systems. The British Geological Survey has warned that this is the largest solar storm to hit the planet in over 20 years, and it has upgraded its geomagnetic forecast to the highest intensity level.
The storm, described as a "cannibal storm," is the result of multiple coronal mass ejections from the sun. These large expulsions of solar particles are expected to interact with the Earth's atmosphere, potentially causing disruptions to satellite navigation and communications. Early indications suggest the storm could be one of the most significant since 2005.
In response to the impending solar activity, Nasa has postponed the launch of a mission carrying two Mars-bound spacecraft. The space agency cited the "highly elevated solar activity" as the reason for the delay, as it seeks to ensure the safety of the mission and its payload.
Despite the potential for disruptions, the solar storm may also bring a stunning natural light display to parts of the UK. The Met Office has predicted that the Northern Lights could be visible across much of the country on Wednesday night, following sightings in the northeast on Tuesday.
