Mercury And The Sun

Days before the Leonid meteor shower, Mercury offered another celestial treat, crossing the face of the Sun on November 15, 1999. This event, known as a transit, occurs when Mercury passes directly between the Sun and Earth. While not rare, it requires a filtered telescope to observe the small, dark silhouette of Mercury against the vast solar disk. The next transit will be in 2003.
