German scientists have distributed fifteen telescopes of different types to study the internal structure of a single star in 7 nations of the world. Despite its difficulty, a total of twenty-six astronomers will try to know the age and peculiarities of the chosen star. Fortunately, some stars (including the sun) vibrate and thanks to this vibration, calculating their internal density, the stars can be analyzed. This study began on May 14 and will run until June 24.
