Since his earliest years, Loïc Quesnel has been motivated by two consuming passions: circus arts and astronomy. With a first career as a professional circus artist behind him, he now uses that artistic talent to develop and bring to life the shows and activities at the Planétarium Rio Tinto Alcan. From 2011 to 2018, as a scientific animator, Loïc has also developed astronomy popularization clips for radio, and workshops for learning the secrets of the starry sky. He is now a scientific-leisure coordinator at the Planétarium Rio Tinto Alcan.
