The new series "The Uncharted Universe" of the Austrian Mint is dedicated to physical-astronomical phenomena presented in an unconventional way. The second release features the Black Hole - a mysterious and enormous phenomenon, which exceeds the imagination of man until today. Black holes refer to areas in space where matter has collapsed into itself. By this collapse an enormous amount of mass concentrates on a single point with infinitely high density and an infinitely strong gravitational field, the so-called singularity. The gravity of this area not only curves the space around it, but is also so strong that even light cannot escape it. So far, a distinction is made between supermassive black holes, stellar black holes and intermediate black holes.

The motive of the uniquely shaped coin shows a black hole in color. In order to depict the acting forces as vividly as possible, it was deepened in the center of the coin. The surroundings are depicted in a spiral shape and the elements surrounding the black hole seem to be attracted by the dense mass in the center. The upper edge of the coin features the inscription "SCHWARZES LOCH". The reverse shows a scientific representation of the phenomenon "Black Hole" and terms related to it - "SINGULARITÄT", "15 M", "CYGNUS-X1" and "EREIGNISHORIZONT". The denomination "20 EURO" and the inscription "REPUBLIK ÖSTERREICH" are also part of the design. The Euro silver coin The Black Hole in proof quality is delivered in the original box including a certificate of authenticity.
