Astronomi
Published by Astronomy is the branch of science involving the observation of celestial objects (such as stars, planets, comets, nebulae, star clusters, or galaxies) as well as natural phenomena that occur outside the Earth’s atmosphere (such as the cosmic background radiation (CMB radiation) ). This is basic science studying the various sides of the celestial objects – such as the origin, nature of the physics / chemistry, meteorology, and motion – and how knowledge of these objects to explain the formation and development of the universe.
Astronomy as a science is one of the oldest, as it is known from astronomical artifacts from the prehistoric era, for example the monuments of Egypt and Nubia, or Stonehenge from Britain. People from such early civilizations of Babylonia, Greece, China, India, and Maya was also found to have committed a methodological observations on the night sky. However, despite its long history, astronomy can develop into new branches of modern science through the discovery of the telescope.
Quite a few branches of science ever are included as part of astronomy, and if observed, the nature of these branches are very diverse: from astrometry, space-based shipping, observational astronomy, to the preparation of the calendar and astrology. However, today’s professional astronomy is considered synonymous with astrophysics.
In the 20th century, professional astronomy split into two branches: the astronomical observational and theoretical astronomy. The first involves the collection of data from observations of celestial objects, which will then be analyzed using the basic principles of physics. The second focuses on efforts to develop computer models / analytical in order to explain the properties of celestial objects as well as other natural phenomena. The two branches are complementary – theoretical astronomy seeking to explain the observed results of observational astronomy, and observational astronomy will then try to prove the conclusion made by theoretical astronomy.
Astronomy should be distinguished from astrology, which is the belief that human destiny and affairs related to the position of celestial objects such as stars or rasinya. It is true that these two fields have the same origin, but at present they are very different
