Hey team! In September 2019 I travelled to Aachen, Germany, for a cosmology (space) conference called COSMO-19. My fellow PhD friends and I had a great time seeing the city and attending the conference, and lucky for you, we filmed our whole trip! Enjoy us enjoying this cool city! Until next time, stay safe.
