At the beginning of the 17th century, the invention of the astronomical telescope by Galileo revolutionized our knowledge of the Universe. In the 20th century, with the arrival of rockets, it became possible to travel above the Earth’s atmosphere and observe X-ray and gamma ray radiation, evidence of a hot and violent Universe. Enjoy spellbinding images of the Cosmos.
