The colours of the Cosmos

Light, with its immense, though finite speed, offers to astronomers a precious time machine for disentangling the evolution of the Universe and its celestial bodies since the initial Big-Bang.

As the naturalist reconstructs the biological evolution by comparing the primordial fossils hidden in the deepest layers of the earth, with the more recent and evolved ones found near the surface, so the astronomer collects informations on the primordial Universe by pushing the observation as far as possible. He compares the newly born galaxies observed far away with the “adult” ones seen nearby (“only” few million light years away).

About a century ago a competition started to offer to astronomers gigantic instruments sensitive to any kind of radiation, from gamma-rays to radio waves, to unveil the Cosmos and to better appreciate the variety of phenomena that take place in their full coloured beauty.
