Very cool architecture outside and stunning visuals inside. The planetarium seems a very popular attraction in Buenos Aires. We went on a weekday afternoon, and the queues were insane. You have to book online in advance because you won't get in if you rock up there hoping to pay at the door. The online ticket was only around $2, so it's great value for what you get. You can roam around looking at all the instruments and information, but the show is the highlight. You lie back on your tilted seat, looking upwards at the domed ceiling that turns into a 3D map of the sky in the Southern Hemisphere. They play a 30 minute documentary called 'The birth of planet Earth' which you are totally immersed in, and you feel like you are floating through the galaxy. This is totally all in Spanish and there are no English ones on the schedule, so that's the only reason why it loses 1 star. Luckily for me I had the best interpreter beside me, so I got a lot out of this. You can watch it online yourself later. This planetarium was a thoroughly enjoyable experience. It is also located in a beautiful park with lakes and colourful birds everywhere, which is another bonus. Just a short walk from Plaza Italia.
