As the planets dance in their orbits, Venus passes directly between the Earth and the Sun – always in either June or December – at unmistakable intervals of 8 years; 121 and a half years; or 105 and a half years. The Venus transit of 2004 was photographed by the TRACE satellite, a science probe launched to study the Sun. The next pair of Venus transits will take place in December 2117 and December 2125.

The Morning Star appears to pass across the face of the Sun at regular intervals of 8, 121.5 and 105.5 years. In 2004, NASA's TRACE spacecraft captured the event and in June 2012 humans will see the last transit before the pair in 2117 and 2125.
