New Delhi: Explosive sun storms, called coronal mass ejections or CME is a massive burst of solar wind and magnetic fields rising above the solar corona or being released into space.The burst results in ejection of a plasma consisting primarily of electrons and protons, but may contain small quantities of heavier elements such as helium, oxygen, and even iron.CMEs or Sun storms occur about once a week, with maximum rates of two or more per day. Strong CMEs may profoundly influence space weather and those directed toward our planet can have serious effects.The hints of these explosive sun storms were discovered by spacecraft in the early 1970s.Here are some amazing pics of this natural phenomena released by NASA's Solar Dynamics Observatory throughout the year. 1.An X1-class flare erupts from the right side of the sun in this image captured by NASA's Solar Dynamics Observatory on Nov. 19, 2013.2. A powerful X-class solar flare erupted from the sun on Nov. 19, 2013. 3. A magnetic filament of solar material erupted on the sun in late September. 4. The sun erupted with two of the strongest solar flares it can unleash on Oct. 25 5. Victor Rogus sent in a photo of considerable sunspot activity. 6. The Sun erupted with another Earth-directed coronal mass ejection, or CME, a solar phenomenon on August 21, 2013. 7. The SOHO LASCO C2 instrument captured this image of the Earth-directed coronal mass ejection or CME. 8. The SOHO LASCO C3 instrument captured this coronographic image of the Earth-directed CME. 9. The sun erupted with an X1.7-class solar flare on May 12, 2013. 10. An X1.7-class solar flare erupted from the sun on May 12, 2013. 11. SDO 304 Angstrom image of prominence eruption on the sun at the same time as the X1.7-class solar flare on May 13, 2013. 12. coronal mass ejection (CME) erupted from just around the edge of the sun on May 1, 2013, in a gigantic rolling wave.
