Time Out says
Even when there are no stars in the sky, the Planetarium always gets a 5-star rating, and it remains a good reason to head to Belém and pretend to be in one of those field trips from many years (dare we say light years?) ago. In the sky of the 23-metre dome, you can see constellations, moons, planets, nebulae, galaxies and other parts of the infinite universe.
