What Is a Solar Storm? What happens if a solar storm hits Earth?

A solar storm, also known as a coronal mass ejection (CME), is a powerful burst of energy and particles that is ejected from the Sun’s corona. These storms are typically caused by magnetic activity on the Sun’s surface and can have a range of effects on Earth.

If a solar storm hits Earth, it can cause a number of different effects. The most common effect is an increase in geomagnetic activity, which can lead to the beautiful aurora borealis (Northern Lights) or aurora australis (Southern Lights). However, in more extreme cases, a solar storm can also have more serious effects.

Solar storms can cause disruptions to satellite and communication systems, leading to loss of GPS signals, satellite TV and radio, and other forms of communication. This can have serious consequences for transportation systems, emergency services, and even the economy.

In some cases, solar storms can also cause power outages. When charged particles from a solar storm enter the Earth’s atmosphere, they can create electrical currents that flow through power lines and other electrical systems. This can overload transformers and cause widespread blackouts.

Finally, solar storms can also pose a risk to human health. The increased radiation exposure from a solar storm can pose a risk to astronauts in space, and can also increase radiation exposure for people at high altitudes, such as pilots and frequent flyers.

Overall, while the effects of a solar storm can be beautiful to observe, they can also have serious consequences for our technology and infrastructure. Scientists and engineers are working to develop better ways to predict and prepare for these storms in order to minimize their impact.
