Astronomical organizations - both professionals and amateurs - give award medals to those who deserve it. Schools sometimes give commemorative medals for their students for their achievements or simply for attendance.

The International Year of Astronomy 2009 (IYA2009) is a global celebration of astronomy and its contributions to society and culture and marks the 400th anniversary of the first use of an astronomical telescope by Galileo Galilei.  The aim of the Year is to stimulate worldwide interest, especially among young people, in astronomy and science under the central theme "The Universe, Yours to Discover". IYA2009 events and activities will promote a greater appreciation of the inspirational aspects of astronomy that embody an invaluable shared resource for all nations. For the significant event commemorative coins and medals have been issued in many countries around the world.
