Residents of Sarajevo use a telescope to see Venus transiting across the Sun on June 6, 2012 outside the Bosnian capital. Sky-gazers around the world held up their telescopes and viewing glasses on June 6 to watch Venus slide across the sun — a rare celestial phenomenon that will not happen again for more than 100 years. The spectacle began shortly after 2200 GMT on June 5 in parts of North America, Central America and the northern part of South America, and was seen, with magnification, as a small black dot on the solar surface.
