... The Magnetic Sun . ... Galileo had guessed they were clouds floating in the Sun's atmosphere, obscuring some of its light. ... It turned out that the Sun has a polar field somewhat like the Earth's, but that it reverses its polarity during each 11-year cycle. ... Sunspot fields were evidently produced by electric currents, and it was well known that such currents could be generated by a " dynamo process ," by the motion of an electric conductor (e.g. the flow of solar plasma) through a magnetic...

These spots appear dark in photographs like the one above, but in fact sunspots are quite bright - they are just dark compared to the rest of the Sun. ... This field slows energy from entering the sunspot region, causing sunspots to appear cooler, darker, and lower than the surrounding surface. ... The Sun and sunspots should never be looked at directly . ... About APOD > . ...

... The storm began quite unexpectedly. The strongest geomagnetic storm for the last seven months began on Earth almost precisely at the same time as the solar eclipse reached its maximal stage, the culmination of which occurred at GMT 02:35 (06:35 Moscow time). ... Oscillations of such amplitude in the magnetic field have not been observed since October, 11th of last year, which is more than seven months ago. ...

The plasma relaxes for a crossing time (118 Myr) and then we inject mass and x-momentum to a central control cylinder and experiment with the jets power: velociB µG RM maps We calculate RM= 812 dl rad m-2 from the jets' con3 tact discontinuity to the end of the domain along different viewing angles. ...

Most current theories for magnetospheric emission can be grouped into polar cap, outer gap, and nebular models. These models, at least in some cases, need not be mutually exclusive; the Crab pulsar (among others), for example, shows clear evidence for pulsed emission from the magnetosphere and unpulsed emission from the surrounding nebula. ... This suggestion is strengthened by observation of a distinct soft emission component, consistent with the cooling scenario, from several of these pulsars. ...
