Friends who are interested in astronomy may wish to take a walk in the Planetarium of the Provincial Women and Children Activity Center during the Spring Festival. Yesterday, the reporter learned from the planetarium that the ball curtain and celestial demonstration program in the museum have been completely updated.

Among them, the most striking is the demonstration of three newly added spherical screen celestial bodies. One is "Comet and Meteor Shower", which mainly demonstrates the famous comets in history, introduces the ins and outs of comets, the relationship between comets and meteors, and demonstrates spectacular meteor showers. The other is the sun, moon and stars, which mainly demonstrates the most common celestial bodies in the sky, such as the sun, moon, stars and planets.

By demonstrating the operation rules of these celestial bodies, the program brings the audience into the mysterious astronomical world from the shallow to the deep. The third is "asteroid exploration", which mainly demonstrates the origin of mysterious celestial bodies such as asteroids and reveals the secrets of celestial bodies hitting the earth and the extinction of dinosaurs.
