Magnetic Portals Connect Sun and Earth

MaxwellEdison writes "Scientists have discovered evidence of magnetic portals connecting the Earth and the Sun every 8 minutes. 'Several speakers at the Workshop have outlined how FTEs form: 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.'"

      Sorry, headline is correct. The Earth's magnetic field lines and the Sun's field lines are connecting every 8 minutes. The fact that they connect allows a stream of the solar wind into the Earth's magnetosphere and/or atmosphere. The article clearly states that the magnetic field of the sun and the earth become coupled every 8 minutes. Since this is an article posted on nasa.gov I'd like to assume that it isn't just another example of bad science journalism. Especially since it makes sense ;)

    2. Re:8.32 light minutes by NotNormallyNormal · · Score: 3, Insightful
      Unfortunately, this 8 minutes would have nothing to do with the speed of light. The magnetic field emanating from the sun (interplanetary magnetic field) is 'frozen-in' to the plasma streaming out from the sun (solar wind). The solar wind velocity is usually between 300 and 700 km/s - this makes the trip MUCH longer than 8 minutes.

      The frozen-in condition follows from Maxwell's equations. Data from the ACE satellite show this is exactly the case. Therefore, as the solar wind speed increases, the IMF will reach the Earth faster. In the case of major solar events - such as coronal mass ejections (CME) - the solar wind speed is usually very high and we see the effects of the magnetic field and particles about 1 day after the 'light' (X-rays, visible light, etc) reaches the Earth.

  25. Use for planet detection? by Anonymous Coward · · Score: 4, Interesting

    Exactly!

    Could this be used to detect planets (which have a magnetic field)? The delay between subsequent magnetic portal anomalies should give approximate distance from central Sun to the planet.

    And do other planets (with magnetic fields) exhibit this magnetic portal as well? Then the Sun should somehow contain a magnetic "signal" which is a superposition of all of those. With Fourier analysis we should be able to make out the components, thus finding out how many planets (with magnetic fields) there are and their distances from the central star.

    And a bit more sci-fi idea: could we use this for communication purposes - make the Sun or the portal "ring" with our message? Kind of like lighting a big enough lamp to be seen from a further distance.

    And something to think about: how do binary stars behave... Are they in resonance?
