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.
This photo (below) shows the Earth in size comparison for the idiots that think that SUV's and cow flatulence are responsible for all weather events and the Sun has nothing to do with it.
