Could a Solar Flare Destroy Earth?

Solar flares sound scary, but they won't exactly destroy the Earth. The Sun's occasional eruptions could reach our planet if they are especially powerful, and at that point may cause damage to power grids.

Would a solar flare wipe out life on Earth?

Fortunately, no matter what, flares do not have a significant effect on us here on Earth. The Earth's atmosphere more or less acts as a shield to prevent the cosmic radiation from reaching us. There can be measurable effects at ground level, but the amount of radiation is pretty insignificant.

What damage can a solar flare do to the earth?

Strong solar flares can send huge clouds of plasma into space. This is known as a coronal mass ejection (CMEs), and when they hit the Earth they can cause geomagnetic storms and intense aurora.
