solar flare

I witnessed a different topic on television recently. This topic was about solar flares and it freaked me out a bit. I have seen that if the explosions are very intense, the radiation released can disrupt radio communications on Earth and even cause a power outage in the world for a certain period of time. I would like you to be careful and get information about this problem.
