As sunspots emerge on the sun's surface close to its equator, their orientations will match the old magnetic field, while sunspots forming closer to the poles will have a magnetic field matching the ...

Could the expected solar flares bring a greater chance of seeing the northern lights? Sophia Herod takes a look.

But now it works great, and [EmGi] even deposited an array of 64 magnets without using glue to test it out before printing a second one to handle the other polarity. Check out the build/demo video ...

The shift in polarity marks the point at which the sun is halfway through solar maximum, the height of its activity, and the beginning of the shift toward solar minimum. The sun's magnetic field ...

As the time line at right shows, hundreds of times in our planet's history the polarity of the magnetic shield ensheathing the globe has gone from "normal," our current orientation to the north ...
