Huge Magnetic Filament Erupts on the Sun
December 12, 2010: A magnetic filament more than 50 times the Earth’s width is erupting off the surface of the sun. The mega-filament collapsed in a gorgeous cascade of hot plasma between noon and 2 p.m. EST. NASA’s Solar Dynamics Observatory captured a beautiful movie of the eruption (above). The explosion does not appear to be aimed at Earth, so we shouldn’t expect any magnetic storms or satellite troubles.

![matthen:
If you roll a circle inside one 3 times its size, it will actually trace out a 4 pointed star shape called an Astroid (this shape is traced out in the animation in orange). But what if inside the smaller circle, there is an even smaller one tracing out a smaller Astroid? This animation shows the intricate shape that is generated by adding the effects of all the Astroids. [code] [also]](http://25.media.tumblr.com/tumblr_lxggprahmL1qfg7o3o1_400.gif)
