A beautiful prominence eruption producing a coronal mass ejection (CME) shot off the east limb (left side) of the sun on April 16, 2012. Such eruptions are often associated with solar flares, and in this case an M1 class (medium-sized) flare occurred at the same time, peaking at 1:45 PM EDT. The CME was not aimed toward Earth.

Researchers animated this simulation of a magnetic tornado in the solar atmosphere in order to study how such twisters evolve over time and determine how complex magnetic fields manipulate the Suns ionized gas/plasma.

The sun has been producing light for about five billion years but where does all its energy come from? The most common idea is that the sun is burning gas - like a giant fireball in the sky. If this were true, the sun would have gone out long ago. So how is the sun actually fuelling itself? It is converting its own mass into energy. By combining protons (the nucleus of hydrogen) into helium, it squeezes some mass into energy - 4.3 billion kg per second. It is Einstein's famous E=mc^2 which gives us the quantitative relationship between mass and energy, where c is the speed of light.

Solar storms and Northern Lights are in the offing as the sun approaches Solar Max, expected in mid-to-late 2013. Recently, Earth's defenses were tested by a volley of strong eruptions.

NASA's STEREO-B captured these long and feathery jets of super-heated plasma - that extend into the Sun's atmosphere - forming 'Coronal Cells' and then changing back to plumes again.
