University of Padua research team develops system for interstellar communications
Are we really alone in the universe?
Are there traces of past civilisations or precursors to the development of life?
Man and woman have always asked themselves these questions.
Scientific research seeks the answers in different directions. On the one hand with observation from the earth or from satellites around our planet in search of planets where life can develop, called extrasolar planets; in the last twenty years, thousands of them have been identified around stars at different distances from us.
