Magellan

Magellan is a sun badge given for achieving mastery in any 100 skills, formerly 80 (See gallery below) It is the first Sun Badge achievable, and awards 30,000 Energy Points when completed.

Since the update, to achieve mastery, you must complete a mastery challenge. The badge has recently been retired and recreated with the Summer 2013 Khan Academy Update. So users who joined before the Learning Dashboard come out would get double points if they had this badge before.

Name
The badge was named after Ferdinand Magellan. He traveled three-fourths of the world and tried to discover Terra Australis, until he was killed by natives from an island in the Pacific. Despite this, he's credited with the first cirumnavigation of Earth. Because of this, the icon for Magellan has a ship's wheel on it.

Trivia

 * After the learning dashboard was added, they retired the old version of this badge and made a new one. Because of this, it is possible to obtain two copies of this badge: One retired, one current.
