Our Sun is an incredible ball of hot plasma that provides the energy needed for life on Earth. Without it, our planet would be a cold, lifeless rock. But the Sun can also affect us in other ways. Sometimes, it sends out bursts of energy and particles that can disturb Earth’s magnetic field. These disturbances are known as solar storms, and they can have a big impact on our planet.
Solar storms happen when the Sun releases a huge amount of energy and particles into space. One of the main causes is a coronal mass ejection (CME), which is when the Sun’s outer layer, or corona, ejects billions of tons of electrified gas at high speeds. When these charged particles reach Earth, they can create beautiful lights in the sky called auroras. However, they can also cause problems.
Throughout history, solar storms have shown us their power. In 1859, a massive solar storm known as the Carrington Event hit Earth. It was so strong that people saw auroras all over the world. The storm traveled the 150 million kilometers from the Sun to Earth in less than 18 hours. It disrupted telegraph systems in Europe and North America, even giving operators electric shocks!
More recently, in 1989, a solar storm caused a power blackout in Canada, leaving millions without electricity for hours. In Sweden, solar storms in 2003 and 2015 led to power outages and disrupted air travel. These events show us that solar storms can have serious effects on our modern world.
If a solar storm as powerful as the Carrington Event happened today, it could cause major problems. It might disrupt satellites, airline operations, navigation systems, and the electric power grid. Millions of people could be left without electricity or communication for months or even years. This is why it’s important to understand and prepare for these events.
Thankfully, scientists and organizations are working hard to protect us from solar storms. Agencies like NASA and the National Oceanic and Atmospheric Administration (NOAA) use advanced satellites and models to track space weather. They aim to predict solar storms before they reach Earth, giving us time to prepare.
Since 2013, researchers have been able to share their CME forecasts in real time, thanks to the CME Scoreboard run by NASA’s Goddard Space Flight Center. This helps us stay informed about potential solar storms heading our way.
In 2019, the United States Senate passed the Space Weather Research and Forecasting Act. This law aims to improve our ability to predict and deal with space weather events. While there’s still much to learn, the future looks promising for better solar storm predictions.
Understanding solar storms is crucial as we rely more on technology. By studying and preparing for these events, we can protect our world from their potential dangers.
Design an infographic that explains what solar storms are, how they occur, and their potential impacts on Earth. Use visuals to illustrate concepts like coronal mass ejections and auroras. Share your infographic with the class to help others understand the importance of solar storm preparedness.
Choose a historical solar storm event, such as the Carrington Event or the 1989 Canadian blackout. Research the event in detail and prepare a short presentation for the class. Include information on how the storm affected technology and daily life at the time.
Work in groups to simulate the impact of a solar storm on modern technology. Assign roles such as power grid operators, satellite technicians, and emergency responders. Discuss how each group would respond to minimize the storm’s effects and ensure public safety.
Prepare a list of questions about solar storms and space weather forecasting. Conduct an interview with a scientist or researcher in the field, either in person or via video call. Share the insights you gain with your classmates, highlighting the importance of ongoing research.
Create a plan for how your community could prepare for a major solar storm. Consider factors like communication, power supply, and emergency services. Present your plan to the class, explaining how it could help mitigate the storm’s impact on daily life.

[Music] Our Sun, a nearly perfect sphere of hot plasma, is by far the most important source of energy for life on our planet. Without it, Earth would be a cold, lifeless chunk of rock. However, there are other ways the Sun could affect us. Radiation storms and ejections from the Sun can cause disturbances in the Earth’s magnetic field. A powerful geomagnetic storm, commonly referred to as a solar storm, is a temporary disturbance of the Earth’s magnetosphere caused by a solar wind shockwave or cloud of magnetic field. These storms often occur when a coronal mass ejection (CME) sweeps past Earth, causing the magnetic field to become unsettled.
Coronal mass ejections eject material from the Sun’s corona, sending billions of tons of electrified gas shooting away at incredible speeds. When charged particles from a CME reach areas near Earth, they can trigger intense lights in the sky called auroras. Throughout history, we’ve seen the dangerous impact these storms have on Earth. In 1859, the first known modern occurrence of a solar storm impacted Earth, with auroras seen around the globe. This CME traveled 150 million kilometers between the Sun and Earth in less than 18 hours. Today, it’s known as the Carrington Event and is remembered as one of the most powerful solar explosions ever recorded.
How powerful, you might ask? When the shockwave of accelerated particles arrived, the disturbances to Earth’s magnetosphere were so great that telegraph communications across Europe and North America experienced disruptions, and in some cases, operators received electric shocks. Other solar storms of this scale or smaller have occurred over the past century. Researchers in the field have discovered that these events are more frequent than previously thought. More recently, a space weather event in 1989 triggered an electric power blackout in Canada, resulting in millions of people without power for hours and causing damage to some electric power transformers and other grid components in Canada and the United States.
In Sweden, space weather events in 2003 and 2015 resulted in electric power blackouts, rerouting of commercial flights, and the closure of Swedish airspace for more than an hour. A more thorough assessment is needed to identify vulnerabilities to the effects of space weather events as we increasingly depend on electronic infrastructure. A CME with the proportions of the Carrington Event could wreak havoc on numerous sectors. According to the Federal Emergency Management Agency of the United States, a geomagnetic storm of this intensity today would be a catastrophe in slow motion, affecting satellites, airline operators, manned space flights, navigation systems, and the electric power grid. It could leave millions of people without electricity or communications for months or even years.
However, there are efforts underway to protect us. We have made significant progress in preparing for and predicting space weather events on Earth. The National Oceanic and Atmospheric Administration, NASA, and other organizations use advanced satellite systems and models to assess space weather events. While we track CMEs with a number of instruments, the sheer size of the solar system means that our observations are limited and usually taken from a distance. NASA researchers aim to improve our understanding of CMEs and how they move through space. Since 2013, researchers working on CME models around the world have been able to post their forecasts publicly in real time before the CME reaches Earth. The CME Scoreboard, run by the Community Coordinated Modeling Center at NASA Goddard Space Flight Center, acts as a live feed of CME predictions heading for Earth.
[Music] In 2019, the United States Senate passed the Space Weather Research and Forecasting Act. This bill sets forth provisions concerning improving the ability of the United States to forecast space weather events and mitigate their effects. Although there is still much work to be done, the future looks bright for more accurate space weather predictions.
