NEUTRON STAR Uncharted Universe Silver Coin 20€ Euro Austria 2023

The reverse of the coin depicts a wonderful coloured image of the Neutron star. This fascinating phenomenon happen from supernova explosions, when a massive star collapses and the overwhelming gravity compresses the nucleus. The neutron star can thus be understood as a gigantic atomic nucleus with a radius of 10 to 12 km. To represent it in a simplified plastic way, the coin was provided with a hemisphere that curves outward on one side and inward on the other. The surrounding area shows the magnetic field of the rotating neutron star as well as stylized stars. On the top left of the reverse, the inscription: "NEUTRONENSTERN"- the name of the coin. The obverse of the coin shows the "crust" and the "core" of the neutron star as well as the inscription "KREBSPULSAR" - the name of a neutron star that was formed from a supernova in the year 1054. All around the obverse, the inscriptions: "2023"– the year of issue, "REPUBLIK OSTERREICH" – the issue country and "20 EURO" – the face value.
