These three images show a coronal mass ejection, or CME, erupting into space on May 26, 2013. The pictures were captured by the ESA/NASA Solar Heliospheric Observatory with its coronagraph, which blocks out the bright light of the sun to better see its dimmer atmosphere, the corona.

On May 26, 2013 at 3:24 p.m. EDT, the sun erupted with a coronal mass ejection or CME, a solar phenomenon that can send billions of tons of solar particles into space that can affect electronic systems in satellites. Experimental NASA research models show that the CME was not Earth-directed and it left the sun at 550 miles per second. It may, however, pass by STEREO A and its mission operators have been notified. The spacecraft can be put into safe mode if warranted.
