Short Description about Institute of Astronomy, Sri Lanka (IOAS)

Institute of Astronomy is the first-ever astronomical learning institute in Sri Lanka which is organized for local students and adults. From this institute,  we have inaugurated Astronomy school for local students since December 2018 and also astronomy certificate courses. Especially, we designed an open lecture series for students and adults every month and it is also we offer freely. On the other hand, we are developing techniques of research methods and data analysis methods. Due to its quality and high academic structure, our institute has designated as the main astronomical learning institute in Sri Lanka.
