Transit of Venus Today (in Pictures)
June 7, 2012
- article by Avi AbramsJune 6, 2012 - The Last Transit of our Lifetime Something lovely happens in the skies today... Venus is a strangely errant planet, having the most complicated orbit when observed from Earth. We are lucky to observe this transit (basically the "Venus eclipse of the Sun") in our lifetime. The next one going to occur only in 2117. Here is the NASA image captured June 6, 2012 (SDO's Ultra-high Definition View of 2012 Venus Transit - 171 Angstrom):(images credit: NASA Goddard Photo and Video) Gives you the proper sense of scale, doesn't it? Incredible detail revealed in this NASA/JAXA (Japanese space agency) spacecraft Hinode's photo:(images via) "Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that repeats every 243 years. A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than 3 times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth." This is how it was illustrated by Nitzschke (see quite large collection of historical Transit of Venus illustrations here): An glorious depiction of the Transit of Venus June 6th, 1761, conjoined Mercury, by Johann Gabriel Doppelmayr. First published in Atlas von hundert Charten 1712 & reprinted in Grossen Atlas 1716: "Crabtree watching the Transit of Venus A.D. 1639" by Ford Madox Brown, a mural at Manchester Town Hall:(image via) Also check out this fabulous plate from observations in Guadalajara, Mexico, courtesy of Durruty Jesus de Alba Martinez:(image via) This year it will only visible in some parts of the globe, and in North America the transit has already occurred during sunset, June 5th... "Timing the transit from two widely separated places on the Earth’s surface allows you to work out the distance to Venus and hence the size of the solar system":...
