The term “space weather” was coined to describe the dynamic conditions in the Earth’s outer space environment, in the same way that “weather” and “climate” refer to conditions in Earth’s lower atmosphere.
Space weather includes any and all conditions and events on the sun, in the solar wind, in near-Earth space and in our upper atmosphere that can affect space-borne and ground-based technological systems.
Measuring and analyzing space weather is important to our national economy because solar storms can affect the advanced technology we have become so dependent upon in our everyday lives. Energy and radiation from solar flares and coronal mass ejections can also harm astronauts in space.
Below is the latest news on geomagnetic storms and solar flares including risks to electrical grids, astronauts, satellites and more.
