As part of International Day of Planetariums, QVMAG Planetarium coordinator Martin George will present a free public talk on Saturday and Sunday at 12.30pm.

The talk allows people to get up to date on what's happening in astronomy and space research. They will be able to find out about the largest known space explosion, hundreds of new satellites in orbit, how we discover planets belonging to other stars.

It is estimated that more than 152 million people visited planetariums last year worldwide.

The event is run by the International Planetarium Society, and aims to promote knowledge of planetariums by bringing the magic of astronomy to everyone.

Dr George said the goal of the International Day of Planetarium was to inform the public about planetariums: what they are and why they exist; to educate the public about the problem of light pollution; and to promote international exchanges and collaborations between planetariums of different countries.

"The role of planetariums is more relevant today than ever. With the advances in our knowledge of the universe, better space technology than ever before, and the excitement of a possible human return to the Moon, planetariums are the ideal places to learn of these great steps forward," Dr George said.

Planetarium shows run as normal on Saturday. On Sunday, four events will be held at 10.30am, 11.30am, 1.30pm and 2.30. The first show is most suited for children.

The rest of the shows have an age limit of five and above.
