What is a Solar Storm?

A solar storm is a term used for atmospheric effects felt on Earth from certain events that occur on the Sun.

You probably think of the Sun as a bright shining light that never changes.

In reality, it's an unbelievably huge ball of molten gases that's constantly in flux.

Solar storms occur when the Sun emits huge bursts of energy in the form of solar flares and coronal mass ejections.

These phenomena send a stream of electrical charges and magnetic fields toward the Earth at a speed of about three million miles per hour.

When a solar storm strikes the Earth, it often produces a dazzling “northern lights" display in parts of the atmosphere that can be seen in areas close to the Arctic Circle.

Solar storms can also disrupt satellites and various forms of electronic communications. Solar storms start with a huge explosion on the Sun.

These explosions called solar flares can be about as powerful as billions of nuclear bombs.

Solar flares usually go hand-in-hand with the release of huge streams of charged plasma that travel at millions of miles per hour.

These streams are called coronal mass ejections, or CMEs. When CMEs hit the Earth, they can cause geomagnetic storms that disrupt satellites and electrical power grids.
