Trail of the Universe
The Trail of the Planets has been extended by adding the Trial of the Universe, a 450 m loop through the forest which allows excursionists to stroll through the entire universe, both in terms of space and of time.
10 large panels are positioned along the route illustrating the stars, nebulae, clusters and galaxies, in the same scale used in the Trail of the Planets. The itinerary can be walked in either direction, i.e. either upwards, and thus starting the imaginary journey with the Big Bang and the creation of the Universe and up to today, arriving at our Sun positioned at the Observatory, or alternatively, travelling backwards in time and space.
In the latter case, you encounter the stars closest to us first (Sirius and the Pleiades) and then move on among the spirals of the Milky Way, among nebulae and clusters (M42 and M13). After an imaginary journey of 2 million light years, you reach the nearest galaxy to the Earth, Andromeda (M31), the clusters and super clusters of other galaxies and distant quasars (3C273), and on to the furthest borders of the Universe when matter, time and space did not yet exist.
