Hello Internet Traveller! I am Helena Villares, in this website you will find my Erasmus+ project for Technological branch students "Touching the past to reach the future" in which Pompeu Fabra High School in Martorell, Spain, is participating during this school year 2021-2022. Our Erasmus+ partner schools are from Greece, Italy, Czech Republic and Spain. Some of the project objectives are: To create a Sky Sphere with positions of my Supernova and exoplanets. To analyse a light curve and a Doppler spectrum to know radius and mass of my exoplanets from my constellations. To analyse a X-Ray Spectrum of RX J1713.7-3946 Supernova in order to obtain its chemical composition. Here you will see my Skysphere with sky objects from the following four constellations: Sagittarius Scorpius Sculptor Scutum
