Explain the difference between pulsating variable stars and eclipsing variable stars.

Pulsating variable stars go through periods of swelling and brightening, then shrinking and dimming. The absolute magnitude of pulsating variable stars changes. Eclipsing variable stars are pairs of stars that orbit each other. When one star moves in front of the other, it eclipses the other star, thus causing the apparent brightness to dim. The apparent magnitude of eclipsing variable stars changes.

The positions of the stars and other heavenly bodies are studied by astrologists and used in astrology. Does that mean it is wrong for a Christian to study the heavens? Explain your answer.

Christians can study the heavens just as they study the earth. People who study and practice astrology trust the stars and other heavenly bodies for guidance. The Bible is the Word of God, and since God is unchangeable, the Bible applies to people today. God tells us that the Bible should be “a light unto [our] path” (Ps. 119:105). Christians should not look for guidance from sources, such as horoscopes, that do not agree with God’s Word.
