The Hong Kong Observatory delves into astronomy to deliver moon-watching tips for the upcoming Mid-Autumn Festival, and shares the science behind its observations in popular classes.

All eyes will be on the skies on the eve of September 8, as families gather to celebrate the Mid-Autumn Festival and observe the full moon.
