Stamps with Rock Dust - Update

Category - Touch
Subcategory - Stamps with matter affixed - Rock dust 

Norway 2009 – Astronomy Europa Stamps MS with real meteorite dust printed.     

Issue date 12 June 2009  
 The subject of the miniature sheet is a solar eclipse, where the Moon passes between the Earth and the Sun. The graphic presentation on the miniature sheet shows the planets in our solar system, with their relative size, surrounded by the largest moons. The table gives their maximum and minimum distances from the Sun and the number of years it takes the planets to circle the Sun.

The stamp shows an explosion on the Sun. As a result of such explosions, solar storms occur. These are streams of charged particles ejected from the Sun, usually at relatively low speeds but sometimes considerably faster. Clouds of electrons and protons are hurled towards Earth and this can affect, for example, space satellites.

The average distance from the Moon to the Earth is 384,400 km. It is always the same side of the Moon that faces the Earth. The first men on the Moon were American astronauts Neil Armstrong and Edwin (Buzz) Aldrin, who landed there with Apollo 11 on 21 July 1969.

Real meteorite dust has been sprinkled beside the country name on both stamps. Meteorites are about 4.6 million years old, much older than the oldest rocks that have been found on earth.
