An Introduction to Astronomy-oriented undergraduate liberal arts school set up a comprehensive electives is for non-astronomy students basic knowledge of the spread of modern astronomy courses. Astronomy research results directly to the people living in the service of humanity on the earth, while it and other disciplines have a wide range of mutual penetration, the relationship between development, in which the relationship between mathematics and physics, the most prominent, astronomy and socio-political, religious , culture, art and other fields also have a long relationship. Thus, a basic knowledge of astronomy, for the noble pursuit of knowledge and literacy of contemporary people, regardless of whatever their occupation, are worthy of study.

Introduction to astronomy through the study and observation, so that a more systematic access to higher education undergraduate students on a variety of celestial bodies and the universe of knowledge, scientific understanding of the mysterious and harmonious universe, to know the universe of human existence the environment, human exploration of the universe of scientific methods, hard history and future prospects, and thus broaden their horizons, inspired life, and establish a right outlook on the world, improve the scientific quality and comprehensive level of knowledge

Include celestial coordinates, time series, the Sun and planetary systems, stars, galaxies, new vision of contemporary astronomy, the 20th century astronomy, the four found in 60 years, the stars of energy and evolution mechanisms, black holes, extraterrestrial civilizations and explore the universe model and theory.

Common basic use ordinary telescopes, constellation identification method of practice, observation of the nine planets of the sun and sunspot observations, Mercury or Venus transit observations, sun and moon eclipse observations, the Galaxy and Hewaixingji observations, comets, meteor shower and other astronomical phenomena observations, celestial observation and study of spectra, as well as simple design of telescope making techniques.

A brief history of human exploration of the universe, center of the earth said that the Japanese star, said Galileo, Copernicus, Newton, Einstein, Hubble, Hawking and others were an vital contribution to the history of astronomy.

Study objects outside the Earth’s atmosphere and the universe, as well as on the ground hard to achieve laboratory the extreme physical and chemical state and evolution of celestial bodies mechanism.

The three main branches of astronomy are: astrometry, celestial mechanics and astrophysics. Mainly based on observation of its research methods, combined with a comprehensive theoretical analysis.

Understanding of the Earth-Moon system, the solar system, stars, galaxies and Hewaixingxi.

Celestial coordinates of setting up the basic principles of three kinds of commonly used in celestial coordinates, celestial bodies and the sun’s apparent motion, celestial equatorial coordinate system itself is movement.

Teaching points:
Understanding of the star when the sun with the flat and conversion, the district with the world, the calendar and the modern time services.

To know law of universal gravitation and planetary equations of motion, planetary orbits and, as the law of motion, interplanetary spacecraft’s orbit and the solar system small bodies.

Two-body problem in the relationship between speed and track, three kinds of universe, the speed of modern space technology profile.

This chapter focuses on master the law of universal gravitation, Kepler’s laws of planetary motion, the planet’s apparent motion laws of eclipses, as well as small bodies of the solar system.

Your online Astronomy, Sky, Star, Saturn and more information. Enjoy!
