Eruptive events on the Sun can be wildly different. Some come just with a solar flare, some with an additional ejection of solar material (called a coronal mass ejection – CME), and some with complex moving structures in association with changes in magnetic field lines that loop up into the Sun’s atmosphere, the corona. On July 19, 2012, an eruption occurred on the sun that produced all three. Watch the video…
A giant Solar Eruption the size of 20 Earths, on Dec. 31, 2012. The length of the eruption extends about 160,000 miles out from the Sun. The Earth is superimposed on this image to give readers a sense of the scale. Image © NASA/SDO/Steele Hill
This NASA montage of New Horizons images shows Jupiter and its volcanic moon Io, taken during the spacecraft’s Jupiter flyby in early 2007. The image shows a major eruption in progress on Io’s night side, at the northern volcano Tvashtar. Incandescent lava glows red beneath a volcanic plume, whose uppermost portions are illuminated by sunlight. The plume appears blue due to scattering of light by small particles within it.

A spectacular fire show started last night when Nyamuragira volcano (also known as Nyamulagira) began an eruption that happens about every two years. The eruption could be seen clearly from park headquarters – probably the best view you could ask for.
This is a view of coloured water caused by lava and gas emissions coming from the eruption of an underwater volcano in the waters of the Calmas Sea off the coast of Hierro Island, in the Canary Islands. According to experts the gases did not present a danger to the island’s 10,000 residents.
The Sun unleashed an M-2 (medium-sized) solar flare, an S1-class radiation storm and a spectacular coronal mass ejection (CME) on June 7, 2011. The large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface as this image, taken by the Solar Dynamics Observatory, shows.
Lightning strikes in the erupting Grímsvötn volcano. The picture was taken from Orvar Atli Thorgeirsson, from the area of Sprengisandur, in the central highlands of Iceland, 60km away from the eruption.
