10Then the third angel sounded his trumpet, and a great star burning like a torch fell from heaven and landed on a third of the rivers and on the springs of water.
11The name of the star is Wormwood. A third of the waters turned bitter like wormwood oil, and many people died from the bitter waters.
12Then the fourth angel sounded his trumpet, and a third of the sun and moon and stars were struck. A third of the stars were darkened, a third of the day was without light, and a third of the night as well.
— Revelation 8:10-12
