Magnificent CME Erupts on the Sun (IMAGE) University of New Hampshire Caption An image from NASA Solar Dynamics Observatory (SDO) satellite that shows an example of a commonly believed Slinky-like shaped coronal mass ejection (CME) -- in this case a long filament of solar material hovering in the sun's atmosphere, or corona. This CME traveled 900 miles per second connecting with Earth's magnetic environment and causing aurora to appear four days later on Sept. 3, 2012.
