The pioneering space experiences will be the ultimate voyage to encounter new planets around distant stars. Theirs will be the journey into the extraordinary. On distant planets are incandescent storms big enough to swallow the earth. Bolts of lightning thousands of miles long. Raging infernos of toxic gas. Inconceivable violence and terrifying extremes. These are the planets from hell.

SDO Year 2 HD
April 21, 2012 marks the two-year anniversary of the Solar Dynamics Observatory (SDO) First Light press conference, where NASA revealed the first images taken by the spacecraft. This video highlights just some of the amazing events witnessed in SDO's second year as seen by the Atmospheric Imaging Assembly (AIA) and Helioseismic and Magnetic Imager (HMI) instruments. Segments in red and gold were taken by AIA in 304 and 171 wavelengths, respectively. The growing sunspot segment was recorded by the HMI instrument which views the solar photosphere and transition region.
