To celebrate the last transit of Venus in the 21st century,astronomers and skywatchers came together in many sites around theworld. In the United States , NASA beamed images of the transit from an observatory atop Mauna Kea in Hawaii (just one of many webcasts from many countries) and welcomed thepublic to its various space centers, including the Ames Research Center in Moffett Field, Calif. [ Amazing Venus Transit 2012 Pictures ] "It's truly inspiring to see so many faces here to share thismoment with us," Natalie Batalha, the deputy science teamleader of NASA's planet-hunting Kepler space telescope, toldvisitors at Ames. "It's going to give you, I hope, a profoundfeeling of the grandeur of our own solar system. You're going tosee Venus in person, with a spotlight shining on her." Tuesday's transit began just after 6 p.m.
EDT (2200 GMT) and lastedabout six hours and 40 minutes. It was visible across North America , Europe , Asia and eastern Africa . Because of the International Date Line, some parts of the worldsaw the transit on June 6. A rare celestial sight Venus transits occur when Venus reaches a point in its orbit that brings theplanet directly between the Earth and the sun.
Since the tilt ofVenus' orbit isn't exactly the same as that of Earth, the eventsare rare, occurring just four times every 243 years. The transits occur in pairs eight years apart. Since the June 5transit followed a previous Venus sun crossing in 2004, this is thelast one of the current cycle. Venus and Mercury are the only planets that can be seen crossing the sun from Earthsince their orbits are between our planet and the sun. The nextMercury transit will be on May 9, 2016.
Despite the extreme rarity of Venus transits , they hold a wealth of information about Venus, the sun and oursolar system. Since the first documented observation of a Venustransit in 1639, astronomers have used the events to measure thesize of the solar system, the intricacies of Venus' atmosphere, thewidth of the sun and more.
