All About Astronomy

Posts Tagged ‘solar astronomy

Even though, most people claim that they know what astronomy is but in fact, most of them misunderstand about astronomy. Astronomy and Astrology are NOT THE SAME. While astrology is just a mystical pseudo-science that believes that the heavens can directly affects or influence our daily lives, astronomy is a scientific study of star and universe.

Astronomy is the study of all celestial objects. It is the study of almost every property of the Universe from stars, planets and comets to the largest cosmological structures and phenomena; across the entire electromagnetic spectrum, and more. From the effects of the smallest atoms to the appearance of the Universe on the largest scales.

The only thing we can do to learn the space objects is to observe them. Gathering their light as much as possible and then we analyze the light. We applied known physics law to explain the behavior of the body that emits that light. We can’t do experiment in astronomy, like what we do in physics or chemistry. We can’t increase the stars’ internal pressure to see what will happen. We only can observe the radiation from the object and analyze it, and then we try our best to explain what happen or how it behaves. This uniqueness clearly differ astronomy from any other science.

Astronomy is the oldest of the natural sciences, dating back to antiquity, with its origins in the religious, mythological, and astrological practices of the ancient Early astronomy involved observing the regular patterns of the motions of visible celestial objects, especially the Sun, Moon, stars and naked eye observations of the planets. The changing position of the Sun along the horizon or the changing appearances of stars in the course of the year was used to establish agricultural or ritual calendars.

Astronomy consists of a series of disciplines including:

  1. Solar astronomy: Studies of our own star, the Sun
  2. Planetary science: Studies of the bodies in our own Solar System and those in orbit around other stars
  3. Stellar astronomy: The study of stars and stellar evolution
  4. Galactic astronomy: The study of our own Milky Way and its evolution
  5. Extragalactic astronomy: The study of objects outside of our Milky Way
  6. Cosmology: The study of the Universe as a whole.
