\nThis week, to coincide with the fifteenth annual European Space Weather Week, ESA is celebrating the dynamic phenomenon of space weather.\n<\/p>\n
\nUnpredictable and temperamental, our Sun routinely blasts intense radiation combined with colossal amounts of energetic material in every direction, creating the ever-changing conditions in space known as \u2018space weather\u2019.\n<\/p>\n
\nOur magnetic field protects us from the ‘solar wind’ \u2014 the constant stream of electrons, protons and heavier particles from the Sun – and from Coronal Mass Ejections (CMEs), the Sun\u2019s occasional outbursts of billion-tonne clouds of solar plasma into space.\n<\/p>\n
\nThe most extreme events, arrivals of fast CMEs or high-speed solar-wind streams, disturb our protective magnetic shield, creating geomagnetic storms.\n<\/p>\n
\nThese storms have the potential to cause serious problems for modern technological systems, disrupting or damaging satellites in space and the multitude of services \u2014 like navigation and telecoms \u2014 that rely on them, blacking out power grids and radio communication and creating a radiation hazard for astronauts in space, even serving potentially harmful doses of radiation to astronauts on future missions to the Moon or Mars.\n<\/p>\n
\nWhile these events can\u2019t be stopped, advance warning of an oncoming solar storm would give operators of satellites, power grids and telecom systems time to take protective measures.\n<\/p>\n
\nIn this report, ESA Web TV takes a look at space weather, highlighting how ESA is working to develop new solar-observing missions and help make Europe more resilient to the Sun’s effects on our daily lives.\n<\/p>\n
