Written by Jaša Čalogović Tuesday, 22 November 2016 00:00On November 17, 2016 Dr. Bojan Vršnak participated in the Croatian scientific TV show (HRT-3: "Third Element") entitled "Solar System". In the show, he explained the formation and evolution of the Sun, effects of the solar wind and the solar eruptive processes on the Earth and other objects in the solar system. Various solar-activity effects on the robotic and crewed space missions, including the future missions to Mars, were discussed.
Written by Jaša Čalogović Tuesday, 10 May 2016 00:00The transits of Mercury across the solar disk are rare phenomena, although Mercury orbits the Sun in just 88 days. The reason for this is that Mercury orbits the Sun with the certain angle to the ecliptic, ie. the plane that the Earth orbits the Sun. Mercury transit in Croatia was visible on 9 May 2016, started at 13:12h local time and could be seen for almost 7 hours. Unfortunately, end of transit was not visible from our region because the sunset was at 20:10h and end of transit was at 20:42h. This rare phenomena was possible to observe from Hvar, and it was recoreded in white light and H-alpha using Hvar solar telescope. The next transit of Mercury will be visible from the Croatia in 2019.

The event was organized by the Observatory Hvar and the Elementary School of Hvar, Stari Grad, Jelsa and the Archaeological Museum in Zagreb.
Science Festival is being held for the 14th consecutive year in Croatia and its goal is to bring the science to pupils of primary and secondary schools and the entire interested general public. This year, the Science Festival was organized in 18 cities in Croatia, and it was the second time that city of Hvar hosted it. Compared to the last year, organizers offered a much richer program and the Festival in Hvar lasted for three days, that was visited by students of almost all schools on the island (elementary school of Hvar, Stari Grad and Jelsa).
