Stars are born, evolve and die. Some slowly turn off while others end their days with catastrophic explosions. Such an explosion is called a 'supernova,' and at the instant of the explosion the star shines with the light of a hundred million stars. The remains of the destroyed star expand through space, creating beautiful nebulae called "supernova remnants" that shine for thousands of years.
Issued in a series celebrating the 50th anniversary of Argentina's Consejo Nacional de Investigaciones Científicas y Técnicas, this postal stamp shows the remains of a supernova that astronomers call W44. It was produced when a star exploded about 10 thousand years ago at a distance of 95 million billion kilometers from Earth (10,000 light years).
