Could it be powerful enough to destroy all life on Earth?

The answers are complicated, but Earth’s atmosphere and magnetic field keep us safe even from the most powerful solar flares.

The most dangerous radiation is soaked in the atmosphere long before it touches the ground.

Here are other FAQs about a solar flare and its impacts on Earth’s life.
