Was galaileo burned at the stake?

No, Galileo Galilei was not burned at the stake. He was tried by the Roman Catholic Church for heresy in 1633 due to his support of heliocentrism, which contradicted the Church’s teachings at the time. Instead of execution, he was found guilty and placed under house arrest for the remainder of his life. He continued to work and write during his house arrest until his death in 1642.
