Introduction to the Solar Science Hall: The Solar Science Hall has 12 sets of exhibitions centered around the sun, introducing the structure of the sun, various phenomena of the sun, and the history of solar research. A 20-centimeter-diameter solar telescope is installed in the hall, allowing you to see the sun's corona, prominences, chromosphere and photosphere. The hall encourages viewers to manipulate some of the instruments themselves. The museum also cooperates with various cultural groups in Hong Kong to organize astronomical activities to popularize astronomical knowledge.
