Five years of the sun in three minutes

"On February 11, 2010, NASA launched its Solar Dynamics Observatory -- a spacecraft equipped with sensors, cameras and telescopes all with one mission: an in-depth examination of the star at the centre of our solar system -- the sun. ... Solar flares, coronal mass ejections, sunspots, eruptions; the imaging equipment on the observatory has allowed researchers to see how these evolve and what causes them. Photographs in different wavelengths have allowed researchers to study the sun's plasma, temperatures, magnetic fields and activity, and atmosphere and corona."
