Outdoor Planetarium: Free Telescopes to View the Lunar Eclipse Tonight
The Galileo Galilei Planetarium is your gateway to the universe, and on the night of August 27, it will open its gardens so that both astronomy enthusiasts and casual observers can view the partial lunar eclipse through telescopes, attend talks, and enjoy a projection show on the esplanade.
What to Expect at This Astronomy Night
Throughout the night, in the parks surrounding the Buenos Aires Planetarium and its lake, you’ll find various observation stations equipped with high-powered telescopes —perfect for making out the lunar craters and the gradual advance of the Earth’s shadow.

Since it’s not common in Buenos Aires to see a lunar eclipse—let alone a partial one like the one on the night of Thursday, August 27—you’ll also find astronomers and science communicators from the Planetarium offering live explanations, sharing interesting facts about the partial lunar eclipse over Buenos Aires, and answering questions as the eclipse unfolds.
And as if that weren’t enough, a light show will also take place on the Planetarium’s esplanade to make your night of stargazing truly unique. Telescope viewing will be canceled in case of rain or heavy cloud cover, and admission is free.
