NASA: Strong Solar Flare Earth Impacts Manageable

Impacts of Strong Solar Flares

May 14, 2013 — Given a legitimate need to protect Earth from the most intense forms of space weather -- great bursts of electromagnetic energy and particles that can sometimes stream from the sun -- some people worry that a gigantic "killer solar flare" could hurl enough energy to destroy Earth, but this is not actually possible.


The Solar and Heliospheric Observatory spacecraft captured this image of a solar flare as it erupted from the sun early on Nov 4, 2003. This was the most powerful flare measured with modern methods, classified as an X28. (Credit: ESA and NASA/SOHO)
Solar activity is indeed currently ramping up toward what is known as solar maximum, something that occurs approximately every 11 years. However, this same solar cycle has occurred over millennia so anyone over the age of 11 has already lived through such a solar maximum with no harm.

This is not to say that space weather can't affect our planet. The explosive heat of a solar flare can't make it all the way to our globe, but electromagnetic radiation and energetic particles certainly can.
