Venus Transit, by Paul Haese (Australia): Highly commended in the our solar system category. Perhaps the biggest astronomical event of 2012 was the transit of Venus, which took place in June. Transits occur when Venus passes directly between the Earth and the Sun, appearing as a small black disc passing across the face of our parent star. They occur in pairs, eight years apart, with each pair separated by over a century. The previous transit was in 2004 and the next will not be until December 2117. This is a spectacular view of the active Sun, streaked and blotched with filaments, sunspots and prominences. Venus, a world almost exactly the same size as the Earth, seems dwarfed by the scale and power of our local star
