This unit of study provides a broad understanding of the structure, scale and diversity of the universe and an appreciation of the scientific methods used to achieve this understanding. Current areas of investigation, new ideas and concepts which often receive wide media attention will be used to demonstrate how science attempts to understand new and remote phenomena and how our ideas of our place in the universe are changing., stars, supernova, black holes, galaxies, quasars, cosmology and the Big Bang. It also includes day and night sky observing sessions. 








General Astronomy (1) planetary differentiation of solar system, Sun’s structure and its behavior in the Solar System; Observation (2) astronomical instruments, amateur contribution to scientific research, and an introduction to astronomy photography; Cosmology (3) history of cosmology, Newton and Einstein universe, Hubble law, big bang theory, red shift and geometry of space time; Rocketry (4) Instruments supported to a mission, achievements of particular mission and special theories involved for these particular missions.

    Course code- ASTR210 & ASTR211:   General Astronomy
    This unit discusses about various objects, their structure and their behaviors in the solar system. Different aspects about the sun; solar structure and solar surface activities, magnetic field of the sun, solar neutrinos and solar wind, planetary behavior- precession, liberation, sidereal and synodic periods and retrograde motions of solar system planets along with planetary configurations (elongation, conjunction, opposition, quadrature) and phenomena (tides, seasons, eclipses, aurorae, meteor showers).

Course code- ASTR220 & ASTR221:   Observation
This unit strongly focus on telescope aberrations, useful equations related to telescopes, coordinate systems, spherical astronomy (basic), astrophotography (basic) and time. This unit will show you how to mount a telescope and to use different types of an eyepieces and Barlow lenses.



Course code- ASTR230 & ASTR231:   Cosmology
This course strongly focus on history of cosmology, Newton and Einstein universe, Hubble law, big bang theory, red shift and geometry of space time (basic introduction of general relativity and special relativity) and Kepler's laws of motion to understand the motion of planets in the solar system and extend the Kepler's laws to other star systems. Trigonometric parallax- To understand the basic understanding about one of the earliest methods used to determine the distances to nearby stars using their apparent shift shown within a period of 6 months. Newton's Universal Law of Gravitation- To understand the gravitational force and use it to understand the motion of objects in the universe.


Course code- ASTR240 & ASTR241
This unit strongly focus on development of rocket technology from the first satellite to present.
