Transit of Venus is a rare astronomical phenomena.
Fortunately, unlike the narrow, fleeting path of visibility for a total solar eclipse, the upcoming transit by Venus will last for about 6½ hours and can be seen from more than half of Earth's surface.
On June 5th (in the Western Hemisphere) or June 6th (in the Eastern Hemisphere), Venus will pass across the face of the Sun for the second time in 8 years and for the last time until 2117.
North Americans are positioned to see at least a portion of it on the afternoon of June 5th. Unfortunately, almost everyone in South America will miss out. On the other side of the globe,portions of the transit are observable at or after sunrise on June 6th from Europe, northeast Africa, west and south-central Asia, and western Australia.
The best-positioned skygazers are those in eastern Asia, eastern Australia, Alaska, New Zealand, and all of the Pacific from Hawaii westward. They have ringside seats for watching the entire transit, including the crucial events around both its start and finish.
Though often we're told about a particular astronomical event — eclipses and planet line-ups, for example — that happen only rarely. But Venus crossing the face of the Sun on June 5–6, 2012, takes "rare" to a new level.
Don't miss this chance to see this celestial spectacle, because you'll never have another chance in your lifetime.
To observe the transit of Venus directly you must protect your eyes at all times with proper solar filters.
