Earlier this month, NASA's Solar Dynamics Observatory (SDO) beamed back stunning images of the sun's plasma moving violently around the star's magnetic field for 30 some hours, creating a tornado as large as the Earth itself, with gusts reaching up to 300,000 miles per hour. That's according to Terry Kucera, a solar physicist with NASA’s Goddard Space Flight Center. NPR has more on the makings of solar storms.
