Resumen
Very modern museography, attractive equipment and great astronomical pictures are the signatures of the new astronomy exhibit in Universum, the Science Museum at UNAM. Up-to-date simple descriptions are presented of the Sun and stars, of matter between the stars, of clusters and galaxies, and of the Universe as a whole. The main concept is not limited to the description of each component, but also incorporates the idea that all components, including the Universe, are subject to continuous evolution. In addition a representation of the vastness of space, a time line from the Big Bang to the present epoch, and some video clips from local astronomers are included. It is complemented with a section of the history of astronomy.
