- In 2012, an extreme solar storm nearly hit the Earth
- Researchers studying the event said it could have been more extreme if paired with another event
- Researchers demonstrated how two solar storms could interact with each other
Solar storms could become more powerful if they happen quite close to each other, researchers studying the 2012 solar storm have found.
On July 23, 2012, a solar storm, which NASA describes as the most powerful one in about 150 years, nearly hit the Earth. Had it hit the Earth, it would have caused an economic impact of over $2 trillion and the damages could take years to repair.
The 2012 near-miss has been likened to the 1859 Carrington Event, one of the biggest solar storms on record, that caused auroras as far south as Cuba and Honolulu.
