NASA has turned science fiction into reality, announcing the discovery of real 'portals' in the Earth's magnetic field. In essence, these portals move millions of tons of magnetically charged particles from the Sun provenineti.
'We call them X-points or regions of diffusion of electrons,' said physicist at the University of Iowa Jack Scudder, that they are studying. 'They are places where the Earth's magnetic field connects to the Sun's magnetic field, creating a continuous path that leads from Earth to the atmosphere of the sun 93 million miles away.'
The portals have been observed by NASA's THEMIS aircrafts and probes at distances from ESA's Cluster 10.000 a 30.000 kilometers away from Earth. In 2014, The U.S. space agency will launch a new mission called the Magnetospheric Multiscale Mission (MMS), which will consist of four spacecraft, that will travel around the world to identify and study these points X, in particular areas in which the Earth and the Sun's magnetic fields are formed inexplicably.
'Portali magnetici sono invisibili, instabili e sfuggenti. Si aprono e chiudono senza preavviso e non ci sono indicazioni per guidarci, 'ha detto Scudder. Alcuni dei portali sono minuscoli e scompaiono quasi immediatamente, altri sono grandi e abbastanza stabili.
Nel frattempo Scudder e il suo team hanno calibrato la tecnologia sufficiente per individuare i portali.
