DIRECT : Les insolites : Peut-on voir l’invisible ?

Light carries within it the signature of every substance it encounters on its path. Thus, thanks to light used as a source of information, we don't need to touch the stars or planets to know their composition. On Earth, we can also identify explosive powders or illicit substances. We can analyze the pigments in old paintings and discover the painting techniques used by Leonardo da Vinci. Light invites us on a fabulous journey through time, space, and technology! From the Mona Lisa to galaxies, light invites us on a fabulous journey through time, space, and technology!
