The black disk of the second planet wouldn't crawl across the face of the sun again for more than 100 years. In fact, it's happening again this week--not on Earth, but Saturn. "On Friday, Dec. 21st, there will be a transit of Venus visible from Saturn, and we will be watching it using the Cassini spacecraft," says Phil Nicholson, a Cassini science team member from Cornell ... read more
