The Luminous Mysteries (Mysteries of Light) are a recent addition to the Rosary by Pope John Paul II. They are as follows:
1.) Baptism in the Jordan
2.) Wedding at Cana
3.) Proclamation of the Kingdom
4.) Transfiguration
5.) Institution of the Eucharist
Chronologically, they fall between the Joyful and Sorrowful Mysteries. They are traditionally prayed on the Thursday of each week.
