Lin of video : https://www.youtube.com/watch?v=SNAmniACxb8 🌍 Is there, among the countless stars that illuminate our night sky with a thousand lights, stellar systems identical to ours? Who has never asked himself this question by plunging his gaze into the depths of a starry night. To this day, no one is willing to answer this mystery. However, astronomers who have been interested in this question since antiquity have never ceased to track down, observe and then list each of the stars discovered in the course of their work, even the most insignificant. Although they do not have a reliable answer to share with us concerning the number of stars around us, they are now able to refine their estimates. The latest technological advances, ever more powerful, now allow scientists to refine their figures, and these, as you can imagine, are staggering. Some estimate that there could be over 200 million trillion. 🔥 As a reminder, the videos are published on SUNDAYS at 6:00 PM. ----------
