Transit of Venus

by on Sep.29, 2011, under astronomy, outreach ideas

Amatuer astronomers are already getting excited about next June’s transit of Venus across the sun’s disc.  Why not? It’s only happened 7 times since the telescope was invented (1631, 1639, 1761, 1769, 1874 and 1882 and 2004,) Miss this one and you’ll have to wait 105 years for the next one. Everyone but those in South America and western Africa will have a pretty good view.  Alaska, Western Asia and Oceana will have a particularly good view.

 

 

What will it look like from your location?  When will it happen, answer those questions here.

NASA has a very complete description of the transit here.
