NASA and other EU
institutions are arranged to watch the transit of Venus between 5 and 6 June,
with dozens of activities to capture the best images from this moment not ensue
again until 2117. The transit occurs when Venus passes directly between Earth
and the Sun, which will see the planet as a tiny dot gliding slowly across the
sun king, a phenomenon that was seen by astronomers as Galileo Galilei.
Scientists from the sixteenth and seventeenth observed transits of Mercury and
Venus, the two planets "inside", to measure the distance from Earth
to the Sun in an effort to estimate the size of our solar system.
