Nasa Releases Stunning New Ultra-High Definition Footage Of 2012 Venus Transit -- The Telegraph
One of the rarest astronomical events is captured on film in stunning detail as the planet Venus passes directly between the Sun and Earth, a transit that won't occur again until 2117.
The amazing video was captured by Nasa's Solar Dynamics Observatory (SDO), the most advanced spacecraft ever designed to study the sun.
