Carl Sagan: La Verdad Sobre la Vida en Marte | Conferencias Navideñas (3/6)

Carl Sagan analyzes the history of planetary exploration of Venus and Mars to show how the lack of scientific data historically led to theorizing about nonexistent alien civilizations and channels. Through experiments and data from the Mariner and Viking missions, Sagan explains how Earth's atmosphere and human perception itself distort the reality of space. This video is a Spanish-dubbed version of the third lecture given by Carl Sagan at the Royal Institution on December 3, 1977, as part of his famous Christmas Lectures. The lecture has been adapted to make it accessible to a Spanish-speaking audience. ==== Support the channel on Patreon:   / universable   FOLLOW or SUBSCRIBE to Universable Twitter:   / universabletv   Instagram:   / universable.tv   TikTok:   / universable.tv   About Carl Sagan: Carl Sagan was an influential American astronomer, astrophysicist, and science communicator, renowned for his ability to make the universe accessible to the public.
