Mass ejection
On July 1, 2013, the sun erupted with a coronal mass ejection, or CME -- shown here as the lighter-colored gas moving off to the left -- which soared off in the direction of Venus and Mars. This image was captured by the joint ESA/NASA Solar and Heliospheric Observatory. Credit: ESA and NASA/SOHO
On July 1, 2013, at 6:09 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 based on NASA's Solar Terrestrial Relations Observatory show that the CME was not Earth-directed and it left the sun at around 570 miles per second.
