After a major upgrade and calibration phase, the ASTRI-Horn prototype on Mount Etna has proven to be a highly successful instrument. In addition to the scientific results achieved, the telescope has confirmed the validity of the technologies employed, which are also used by the ASTRI Mini-Array and the SST telescopes of the Cherenkov Telescope Array Observatory (CTAO). It will soon be used as a testbed for the study of volcanoes through Cherenkov muon observations.
ESA’s Jupiter Icy Moons Explorer (Juice) has successfully completed a world-first lunar-Earth flyby, using the gravity of Earth to send it Venus-bound, on a shortcut to Jupiter through the inner Solar System.
The instrument Jovis, Amorum ac Natorum Undique Scrutator (JANUS) passed the commissioning phase with full marks. It is a real test during which – 8 million km from the Earth – it opened its electronic “eyes”, sending the so-called “first light”, i.e. his first series of images, to the technicians and researchers
