Seminar Announcement: The Cosmic Billiard – Meteorites and Their Impacts Apologize for multiple postings - We are one month away! Meteorites are rare objects containing precious information on the origin of our solar system. They preserve evidence of processes that occurred on asteroids in the first few million years of our solar system’s history, but also of later stage events. These asteroids were heated by radioactive decay, leading to thermal metamorphism and release of fluids. They also experienced multiple collisions that left shock damage in the meteorites. Some of these meteorites are finds — often recovered in Antarctica or in hot deserts — but the most pristine ones are observed falls that are quickly recovered after their landing on Earth, preventing terrestrial alteration. We are pleased to announce a five-hours seminar on the meteoritics science with particular emphasis on importance of meteorites related with planetary formation, sample return missions from other celestial bodies, and from Antarctica. Further, the potential threat from near-earth asteroids is small, but not Zero, and as such -and celebrating the recent "Asteroid Day"- the "impact hazards (https://bit.ly/3zdTz4N)" is another unique topic that will be discussed during the event. The seminar will be virtual from Agricultural University of Athens on *Thursday July 7, 2022*.
