In recent years, mental health has emerged as a significant global concern. The neologism "skychology" means interactions with the sky to enhance mental health and well-being. Office of Astronomy for Development has initiated the “Astronomy for Mental Health” project. Studies prove that stargazing significantly benefits our mental health through its calming and meditation effect on the mind. Although the natural sky is irreplaceable, we bring the opportunity to show the beauty of the sky in the planetarium and thus encourage people to observe the stars.
