Galileo is eventually placed on trial and at his old age, is forced to make the journey to Rome. He is under suspicion of "vehement suspicion of heresy," but is convicted of holding and teaching the Copernican belief. He is placed under house arrest for eight years until his death.
He was killed by the french colonists because a mutiny erupted due to the numerous problems that led to the failure of his last mission. Hope this help. Follow and message me for daily answers and help. Hope this helps and good luck. :)
