Looking at the Universe in a different light
Four hundred years after the first observations of celestial bodies through a telescope, the study of cosmic phenomena is carried out only in small part by the observation of visible light. The processes that are the basis of the energy of the universe are mostly studied through the examination of invisible electromagnetic radiation (from radio waves to gamma rays of very high energy), and even through the observation of particles other than electromagnetic radiation. The new telescopes photographing the universe are radically different from the old optical telescopes, and provide new and fascinating images of a universe different from what our eyes can see. And this research is only at the beginning, since now we discovered that we know only a small part of the matter that surrounds us – we are facing a new Copernican revolution: we the humans are not made of the matter that makes up most of the Universe.
In recent years, new instruments of high technology searching for new forms of energy and matter have been placed in orbit, in deserted islands in the middle of the oceans and in the deep sea; images of the cosmos provided by these tools are allowing us to see a new world.
