One thing that we have not fully understood as human beings is astronomy. Astronomy has a way to predict the future keeping mysteries and time that can not be explained all the time. The term "astronomy" is defined as a study of celestial bodies, meaning something in the sky, such as stars, galaxies, comets, planets, nebulae and so on. Even if not everyone, many people will be surprised by the night sky on a sunny, moonless night. Astronomy can be traced back to the ancient times when Babylonians, Egyptians, and Chinese people recorded a record of astronomical events and events.
Definition of astronomy: Astronomy is the study of objects, phenomena other than earth such as the sun, moon, stars, planets, comets, gas, galaxies, gas, dust and other earth. In the K - 4 student 's curriculum, NASA defines astronomy as "research on stars, planets, and the universe." Although astrology and astrology are historically related, astrology is not science, it is believed to have nothing to do with astronomy any longer. Below we discuss related research areas including astronomy history and cosmology.
Astronomy in scientific research, outline of scientific philosophy and scientific method, astronomy without the need for telescope, history of astronomy and science, Newton's gravity law and orbit application, Einstein's relativity theory, electromagnetic radiation, telescope, solar system All objects of the solar system, the nature of the stars, the sun, the nuclear fusion reaction, the star structure, the evolution of stars, the interstellar medium, the structure of the Milky Way, the astronomy outside the Milky Way including active galaxies and quasars, cosmology and extraterrestrial Life There are also examples of angular momentum, review of quick mathematics, improvement of learning skills, astronomical table, astronomical terms page on this site.
Astrophysics and astronomy are applications of the theory and method of physics in the study of star related structures, evolution of stars, the origin of the solar system, and issues related to cosmology. Because astrophysics is a wide field, astrophysicists have many physics fields including dynamics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic molecular physics It is often applied. Karl Jansky discovered that radio waves were radiated from the celestial body in 1931, which led to the development of radio astronomy. Recently space exploration has expanded the forefront of astronomy. Disturbances and interference from the Earth 's atmosphere cause infrared, ultraviolet, gamma ray and X - ray astronomy to require space - based observations
