Matthew 24:29
"But immediately after the terrible trouble of those days, [i.e., the next major event on God's calendar], the sun will become dark, and [therefore] the moon will not [be able to] shed its [reflected] light. The stars will fall from the sky and the forces of the heavens will be shaken [Note: From the description of these same events in Luke 21:25-26, it is possible that this is figurative language for great calamities happening on the earth].
Revelation 8:12
[When] the fourth angel sounded its trumpet [I saw] one third of the sun, one third of the moon, and one third of the stars being struck, so that one third [of their light] would become darkened. So, the daytime had [only] one third of its [normal] light, and the nighttime was the same way.
Matthew 27:51
Just then the Temple curtain was torn in two from top to bottom, the ground shook, and rocks were split open.
Mark 13:24-25
"But after those days of terrible trouble [i.e., the next major event on God's calendar will be], the sun will become dark, and [therefore] the moon will not [be able to] shed its [reflected] light,
Luke 21:25-26
"Then [Note: This event answers to the "immediately" of Matt. 24:29, and suggests the next major event on God's calendar] there will be [supernatural] signs [evident] in the sun and moon and stars. And on earth [there will be] distress among nations; they will be perplexed by the roaring of the ocean's churning waves. [Note: Probably this is figurative language for highly agitated conditions on earth].
Acts 2:20
[In that day] the sun will become dark and the moon will [appear] as blood. [This will all happen] before the great and wonderful day when the Lord comes. [Note: Some view these last two verses as a reference to events occurring at the end of time. See Matt. 24:29-30].
Revelation 6:12
Then I looked as the Lamb broke open the sixth seal, and there [I saw] a great earthquake; the sun turned as black as sackcloth made out of [goat] hair, and the entire moon turned [as red] as blood.
Revelation 20:11
Then I saw a great, white throne and Him who was seated on it [i.e., probably Christ]. Earth and heaven fled from His presence and they were not found anywhere [again].
