The pope's astronomer said the Vatican was keen on science and admitted that the church had got it "spectacularly wrong" over its treatment of the 17th century astronomer Galileo Galilei. Galileo confirmed that the Earth went around the sun – and not the other way around – and was charged with heresy in 1633. He spent the rest of his life under house arrest in Tuscany. Only in 1992 did Pope John Paul admit that the church's treatment of Galileo had been a mistake.Consolmagno said it was a "complete coincidence" that he was speaking at the British Science Festival at the same time as the papal visit.
He is not the only one from Vatican who had raised this issue Father Monsignor Corrado Balducci had also told world media many time that aliens do exist prior to his death.
Monsignor Corrado Balducci, was a Roman Catholic theologian of the Vatican Curia, was a close friend of the pope, long time exorcist for the Archdiocese of Rome, and a Prelate of the Congregation for the Evangelization of Peoples and the Society for the Propagation of the Faith.
He had written several books about the subliminal messages in rock and metal music, diabolic possessions, and extraterrestrials. Monsignor Balducci often had appeared on Italian TV to talk about satanism, religion, and extraterrestrials.
