Observational Astronomy and the basics of Astrophysics are fundamental steps of learning scientific methods and promoting secondary scholars to a science curriculum. Access to such programs is severely limited to the student community of Sri Lanka. The Astronomy and Space Science Unit (ASSU), Department of Physics, University of Colombo intends to offer a series of short courses in Space Science and Observational Astronomy for the benefit of the general public of Sri Lanka.

The course provides an introduction to the field of Astronomy, allowing you to learn about observational astronomy, stars and galaxies, from the Sun to the Milky Way and beyond, and about the structure and formation of the universe. The sky observations and introduction to astronomical instrumentation will be covered in the practical sessions.

The course is prepared for the enthusiastic scholars in astronomy and space science who seek higher education in astronomy and train for the national and international competitions. The course teaches physically and more importantly the hands-on experience of handling modern telescopes and other instrumentations will be given.

The certificate holders shall be able to explain basic laws in astronomy and the present understanding of the solar system up to the galaxies, stellar structures and the universe. Thus, at the end of the course students will be able to:

• Describe or define concepts and astronomical terms from the syllabus
• Explain the natural astronomical phenomena.
• Solve elementary problems in basic astronomy
• Demonstrate elementary skills in measurement, log keeping and instruments.
• Read sky maps and operate astronomical software.
• Read the real sky; identify the constellations, stars and planets.
• Summarize simple scientific information and concepts and draw conclusions. (eg. Following observations and data sets)
