The study of the stars is an ancient tradition that over the centuries has developed into the science we know today – astronomy.
This development includes some events of quite paramount importance. One such milestone was the year 1609, when the Italian mathematician and physicist Galileo Galilei first directed his telescope toward the night sky. To mark the occasion, the UN has designated the year 2009 as the International Year of Astronomy.
The stamp designs are inspired by an international project in which Swedish scientist are playing a leading role: PoGOLite.
The instrument, a polarimeter, will measure polarization in X-rays from space.
One of the first objects to be studied by PoGOLite will be the Crab Nebula. Star charts of the designate the Crab Nebula as M1,
As it was the first object listed by the comet-hunter Charles Messier in his catalogue of phenomena that could be confused with comets.
The schematic diagram of the polarimeter shows how it is made up of hexagonal elements, assembled like a honeycomb.
So that the atmosphere does not block radiation to be measured., PoGOLite will be raised to around 40 km by balloon. This will take place at the Esrange Rocket base in Kiruna, northern

Countless stars embellish the night sky. Stars are the sources of mysterious and amazing legends. Depicted in our imagination, the moon has been where the rabbit mills, but the universe is now revealing its secrets one by one, as mankind’s scientific technology inexorably advances.
Commemorating the 400th anniversary of Galilwo Galilei’s observation of the night sky through a telescope, the UN declared the year 2009 as the “International Year of Astronomy.” IAU (International Astronomical Union) and UNESCO are planning to conduct a campaign in 2009 under the theme of “The Universe, Yours to Discover” in order to celebrate the amazing accomplishments that astronomy has achieved to date and to provide an opportunity to learn about and experience the fascination of astronomy. In about 140 countries around th4e world, a wide variety of activities will unfold in order to enable the citizens of the global village to experience and the beauty of the dark sky and to preserve the natural heritage of the dark night skies.
In commemoration of the “international Year of Astronomy 2009”, a new stamp featuring the mysterious look of the universe is issued. Introduced are: the Planetary Nebula NGC 3132 which looks like a planet but is actually composed of clouds of gases and dust created by the explosion of a star’s unstable outer layer; and the Whirlpool Galaxy M51 composed of hundreds of billions of stars and interstellar matter. How about taking a telescope and looking out the window into the night Sky tonight?
