Revelation 8:11-12

11The name of the star means ‘It tastes bad’. A third of the water on the earth became bad. Many people died because they drank that bad water.

12Then the fourth angel made a sound with his trumpet. A third of the sun became dark. A third of the moon and a third of the stars also became dark. There was no light for a third of the day and there was no light for a third of the night.
