Dec 10, 2021 · Space weather refers to conditions in the solar system produced by the Sun’s activity. Just as weather is always occurring on Earth, space weather is ongoing. Even without major solar activity, satellites and communications systems can be impacted by variability in the density and composition of the near-earth environment. “Space isn’t ...
Jun 11, 2024 · Space weather can affect our daily lives — we need a better warning system. Categorizing geomagnetic storms on a scale of one to five leaves no room for once-a-century superstorms. By. Sean ...

Space weather begins with the Sun. The Sun gives off electromagnetic energy in many wavelengths, including visible light, radio waves, ultraviolet, high energy X-rays, and more. The Sun also emits a stream of radiation in the form of charged particles (plasma) that make up the solar wind. Occasional energy bursts resulting from huge explosions on t...
As the solar wind flows past Earth, it mostly deflects around Earth's magnetosphere, the protective magnetic field that surrounds our fragile planet. Bursts of solar energy that travel toward Earth smash into the magnetosphere, sending particle radiation spiraling down along our planet's magnetic field lines. As these radiation particles collide wi...
Solar flares emit X-rays, among other types of electromagnetic energy. Increased X-ray emissions can scatter radio waves as a result of disruptions to the ionosphere, causing radio blackouts on Earth. Radio blackouts can last for a few minutes or even several hours and are the most common type of space weather impact experienced on Earth. There are...
Solar radiation storms are caused by both solar flares and coronal mass ejections. During a solar radiation storm, large bursts of protons and other particles from the Sun can increase the amount of radiation near Earth to harmful levels that can have dangerous health effects for astronauts at the International Space Station and, in some cases, eve...
A large coronal mass ejection can cause a strong gust of solar wind to reach Earth, transferring energy to Earth’s magnetic field and causing a geomagnetic storm. These storms can create intense currents in Earth’s magnetosphere and cause the ionosphere and upper thermosphereto heat up. The most common effect on Earth is spectacular auroras, but th...
Because of the diverse and complex nature of Space Weather effects, it is impossible to provide detailed descriptions of all the (presently known) primary facets of Space Weather here. The purpose of the review is to briefly give an overview of the full chain of physical processes responsible for Space Weather risks and hazards.
