Aldebaran is a binary star system located 67 light-years from the Sun. It is the brightest star in the constellation of Taurus. Since ancient times, its surroundings have intrigued astrologers, mystics, and poets – and in more recent centuries, astronomers, who long suspected the existence of a planetary system.
The rapid technological advancement of the past two hundred years has not only confirmed the presence of two rocky planets orbiting Aldebaran, but also marked the beginning of the era of exonautics – interstellar travel beyond the Solar System.
The discovered exoplanets were named Tauris a and Tauris b. After several years of observation, clear evidence of a former civilization was detected on the smaller of the two: vast technological ruins scattered across the surface. A significant portion of the planet was covered by a layer of yellow substance that had led to the complete degradation of its biosphere and upper crust. This material was provisionally named exoflavin matter.
Direct surface research revealed that exoflavin is not a natural component of this environment. Its structure and isotopic composition do not correspond to any known chemical processes occurring on Tauris b or in its surroundings. It could not have originated there.
So where did this alien substance come from?
