Astronomy – Out of This World Science
Astronomy is an observational science that studies celestial objects and physical phenomenon around us. It makes use of math, astronomy, and physics in order to describe their orbit, formation, growth, nature, and composition. Objects of common interest among scientists and astronomers include comets, satellites, stars, planets, moon, and other solar-system bodies. It also includes the study of ultra-violet and gamma-ray radiation and its effect on space-based systems.
Astronomy is the study of celestial objects in the visible and ultraviolet regions of the earth’s atmosphere. Astronomy also studies exosphere, which is the outermost layer of the earths atmosphere; and dark matter, which comprises almost 80 % of the earths total mass. Astronomy also includes space exploration, such as exploring the moon, outer planets, outer solar system, and to reach extrasolar planets and stars.
Astronomy utilizes telescopes in order to observe celestial objects. A telescope is designed to correct the position and alignment of the heavenly bodies so that they appear perfectly aligned. Astronomy also relies on astrology, which describes the relationship between heavenly bodies and human beings, such as the birth, death, and creation dates; and mythological and spiritual myths. Astronomy has been a part of human life since ancient times. In fact, the Egyptians built the first observatories and made first maps of the sky.
