Save your money. You can see the best of what this planetarium has to offer for free. What you pay for in purchasing a ticket is to see the films - the first two are interesting but they are quite short. The third is about 30 min and is basically an artistic interpretation of the waves in space...sure cool if you are going to see an art exhibit but for a science exhibition it is just sad. The quest to discover what is out there is fascinating and involves some incredible scientists but clearly this museum has an agenda which is quite political...note the various choices to focus on Quebec scientists and the focus on a Quebec driven artistic interpretation of the science of space. Oh and heads up...if you speak only English be prepared for a choice of 2 early evening (between 3 and 5pm) showings for each show. I'd recommend saving the ticket price and walk through the free stuff then head over and buy a ticket for the biodome and then go up the tower at Olympic place.
