Using information from ESA’s Cluster and Swarm missions along with measurements from the ground, scientists have, for the first time, been able to confirm that curiously named bursty bulk flows are directly connected to abrupt changes in the magnetic field near Earth’s surface, which can cause damage to pipelines and electrical power lines. The magnetosphere is a teardrop-shaped region in space that begins some 65,000 km from Earth on the day side and extends to over 6,000,000 km on the night side... formed through interactions between Earth’s magnetic field and supersonic wind flowing from the Sun. These interactions...comprise complicated magnetic...
