Bit of a sensationalist title, but quite true... the cluster satellites have passed through the magnetosphere of the Earth, pretty cool.
ESA’s Cluster satellites have flown through regions of the Earth’s magnetic field that accelerate electrons to approximately one hundredth the speed of light. The observations present Cluster scientists with their first detection of these events and give them a look at the details of a universal process known as magnetic reconnection.
