The joint ESA and NASA mission the Solar Heliospheric Observatory (SOHO) captured this series of four images of a coronal mass ejection (CME) escaping the sun on the morning of April 25, 2013. The images show the CME from 5:24 a.m. to 6:48 a.m. EDT. This was the second of two CMEs in the space of 12 hours. Both are headed away from Earth toward Mercury. Credit: ESA&NASA/SOHO

On the night of April 24 and the morning of April 25, 2013, the sun erupted with two coronal mass ejections (CMEs), solar phenomena 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 first CME began at 9:30 p.m. EDT on April 24. The second CME began at 5:24 a.m. EDT on April 25. Both left the sun traveling at about 500 miles per second and they are headed in the direction of planet Mercury.
