🇬🇧 – 🇮🇹 In 1902 the archaeologist Spyridon Stais found the Antikythera Mechanism (see detail in the photo), a mechanical device dated between 250 and 100 BC, considered to be the oldest known mechanical calculator. It was originally a sophisticated planetarium, moved by cogwheels, which was used to calculate the rising of the sun, the phases of the moon, the movements of the five planets then known, the equinoxes, the months, the days of the week and – according to a study published on Nature the dates of the Olympic Games. It was found in the wreck of Antikythera, among the remains of a shipwreck that took place in the second quarter of the 1st century BC. near the Greek island of Cerigotto (Antikythira in the local language).

🇬🇧 – 🇮🇹 Herschel Space Observatory: The telescope 1.5 million kilometers away from Earth on a Lissajous orbit in the second Lagrange point of the Sun-Earth system, has collected information about the appearance of the universe in the infrared. The objectives were as follows: to study the formation of galaxies in the early universe and their subsequent evolution, to study the formation of stars and their interaction with interstellar dust, to observe the chemical composition and the atmosphere and surface of comets, planets and satellites, examine the molecular chemistry of the Universe.

🇬🇧 – 🇮🇹 After the sensational image of the black hole of the galaxy M87, today in 2022 the image we have all been waiting for was unveiled: the image of the supermassive black hole at the center of our galaxy known as Sagittarius A, or Sgr A which is about four million times larger than our Sun and is about 27,000 light years from the Earth. It is a collaboration of 300 researchers who together form the EHT collaboration (Event Horizon Telescope) which with the interferometry system connect a network of radio telescopes located in different areas in the world. Here we see in addition to the image of the black hole also the complex system used for the project. Continue in the article! Clicca e leggi il bollettino per gli astronaviganti di oggi!
