what is the difference between astronomy and astrology?

Astronomy is a science that studies everything outside of the earth's atmosphere, such as planets, stars, asteroids, galaxies; and the properties and relationships of those celestial bodies. ... Astrology, on the other hand, is the belief that the positioning of the stars and planets affect the way events occur on earth.

Answer 2

Answer:

A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer's current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° angle.
