In memoriam. Jaan Vennik (1948–2021)
On a beautiful crisp winter morning on February 19, our dear long-time colleague Jaan Vennik passed. Distant galaxies and how they gather to become clusters fascinated Jaan for years, even decades. As many researchers of Tõravere's first generation, he came to study at the University of Tartu as a simple boy, although he had graduated with honors from Tapa's 1st Gymnasium. After receiving his physicist's diploma, he stayed here, and the observatory – no matter what it was called at different times – remained his only workplace.
