Below you can see the image of both sides of this commemorative medal, which has been issued together with a plastic capsule. The medal has a shiny lacquer surface and it's much beautiful to see it live rather than just this image.
The obverse side of this medal (to your left) demonstrates the well known logo of IYA2009. But there are 2 differences, that the logo is not in usual bluish color, this time it's brownish. The other is that the logo is etched in Hungarian. However there's an English version of the text reading International Year of Astronomy along the round edge of the medal.
The reverse is illustrated with the famous Hungarian astronomer Jeno Gothard, who died 100 years ago. Beside the portrait of Gothard, one of his greatest discoveries is also depicted on reverse. In 1892 he came up with the discovery that the spectra of Nova Aurigae is very similar to the spectra of planetary nebula. His drawing from his log book is replicated on this elegant IYA2009 medal.
