Observations by SPACE in INDIA



Scientist over the world will use this rare celestial phenomena to measure the distance between Earth and sun – 1 A.U.  
SPACE will also use this spectacular event to bring appreciation of scientific phenomena and conduct public outreach and education via observations, photography and projects.

What is the Transit of Venus?

A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth, becoming visible against the solar disk, and can be seen from Earth as a small black disk moving across the face of the Sun.
Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years.


A Venus Transit observed with sufficient accuracy from the Earth allows the determination of the distance between the Earth and the Sun. This measure is crucial for astronomers to know because all other distance determinations in the universe ultimately depend on this value. Today astronomers use other, more precise methods for the determination of this "Astronomical Unit - AU", so the present one is above all of historical and didactic interest.

When is the next one?

The next transit of Venus will be on 6 June 2012, and the previous one took place on 8 June 2004 and. After 2012, the next transits of Venus will be in December 2117 and December 2125.[1
