Earth and Sun get connected !

Scientists have discovered a magnetic portal which connects the Earth and the Sun, 93 million miles away ! Tonnes of electromagnetic particles may flow through this portal before it closes. 
This is called FTE, flux transfer event.

Researchers have long known that the Earth and sun must be connected. Earth's magnetosphere (the magnetic bubble that surrounds our planet) is filled with particles from the sun that arrive via the solar wind and penetrate the planet's magnetic defenses. They enter by following magnetic field lines that can be traced from terra firma all the way back to the sun's atmosphere.

The FTEs are predicted to be of two types Active and Passive. On the dayside of Earth (the side closest to the sun), Earth's magnetic field presses against the sun's magnetic field. Approximately every eight minutes, the two fields briefly merge or "reconnect," forming a portal through which particles can flow. The portal takes the form of a magnetic cylinder about as wide as Earth.

The European Space Agency's fleet of four Cluster spacecraft and NASA's five THEMIS probes have flown through and surrounded these cylinders, measuring their dimensions and sensing the particles that shoot through.

There are many unanswered questions: Why do the portals form every 8 minutes? How do magnetic fields inside the cylinder twist and coil?

Meanwhile, high above your head, a new portal is opening, connecting our planet to the sun !
