For the very last time this century, skywatchers and astronomers around the world got the opportunity to witness the rare astronomical reunion of the Sun, Venus and Earth Tuesday. Venus, the second brightest natural object in the night sky after the Moon, made a rare pass in front of the Sun, making its presence in the solar system visible from Earth's day side.
It will be your last change to catch a glimpse of one of the rarest cosmic spectacles -- the slow movement of the planet Venus across the face of the sun.
