On the 13-th of October after 17 days of travelling I got these beautyful stamps on a cover via postcrossing project.
One of them is devoted to the International Astronomy Year. I was especially glad to get t since it's connected with the theme of 2009 Europa stamps.
The stamp features fascinating images from space with a renowned Canadian observatory in the foreground to represent Canada’s important role in astronomy, which includes the co-discovery of the first black hole in outer space. Envelope seals show other haunting space photographs. All of this against a background showing a magnificent picture of the planet Jupiter.
Unfortunately I got nice stamps via postcrossing rather rarely, so this time it was a nice surprice!
Thank you, Weedgenie!
