Today, Venus will appear to dance across the sun, a rare phenomenon called the transit of Venus.
The Venus transit, which will last for nearly seven hours and will look like the sun is being punctured by a small black dot, occurs when Venus crosses between the Sun and the Earth. The last transit took place in 2004, and we won't see another until 2117.

It will be visible from the ground in most of the world except for western Africa, southeastern South America, Portugal and parts of Spain, according to NASA. In North and South America, the transit will be visible on Tuesday afternoon and evening, while Europe, Africa, the Middle East and western and central Asia will see the transit on Wednesday morning.
