Vatican Observatory

Vatican Observatory in its Early Years

The Vatican Observatory celebrated its 125th anniversary on March 14. It was established by Pope Leo XIII on 14 March, 1891, when he promulgated the motu proprio ( i.e., of his own accord, on his own impulse) Ut Mysticam establishing it.

On another note about the Church and Science, the cosmological theory which is today known as The Big Bang was set forth by the Jesuit priest, Fr. Georges Lemaître, who was a pioneer in applying Einstein's Theory of Relativity to cosmology.
