Launched on Feb. 11, 2010, the Solar Dynamics Observatory, or SDO, is the most advanced spacecraft ever designed to study the sun. During its five-year mission, it will examine the sun's atmosphere, magnetic field and also provide a better understanding of the role the sun plays in Earth's atmospheric chemistry and climate. Â SDO provides images with resolution 8 times better than high-definition television and returns more than a terabyte of data each day.
On June 5 2012, SDO collected images of the rarest predictable solar event--the transit of Venus across the face of the sun. Â This event happens in pairs eight years apart that are separated from each other by 105 or 121 years. Â The last transit was in 2004 and the next will not happen until 2117.
The videos and images displayed here are constructed from several wavelengths of extreme ultraviolet light and a portion of the visible spectrum. Â The red colored sun is the 304 angstrom ultraviolet, the golden colored sun is 171 angstrom, the magenta sun is 1700 angstrom, and the orange sun is filtered visible light. Â 304 and 171 show the atmosphere of the sun, which does not appear in the visible part of the spectrum.
