Home to one of the world’s largest all-digital planetarium domes, the Academy is an incredible place to see stars on the big screen. For the real thing, however, few places compare to Chile.
In Big Astronomy: People, Places, Discoveries, journey to three world-class observatories in Chile’s rugged Andes Mountains and arid Atacama Desert—remote, extreme regions that happen to have the perfect conditions for astronomical research. Along the way, you’ll meet an inspiring cast of astronomers, engineers, technicians, and support staff who keep these mega-machines running.
Don't miss the big show—Big Astronomy closes on November 5!
Please note: Planetarium shows may not be appropriate for children under 7, and we regret that we cannot admit any child under 4. Reservations are required: Visit the planetarium page for more information and view our Daily Calendar for showtimes.
We're seeing stars: Big Astronomy won the Best Science Film award at the Dome Fest West Film Festival on October 10, 2021.
There’s a reason Chile is home to about 70% of the world’s astronomy infrastructure: Dry, stable air and clear, dark night skies. These ideal atmospheric and meteorological conditions—plus the virtual absence of light pollution—enable Chilean observatories to view celestial bodies thousands of light-years away.
From keeping 4-meter mirrors spotless to interpreting terabytes of interstellar data, running the world’s largest observatories requires the coordinated efforts of hundreds of passionate, talented people with a constellation of diverse skills.
Big Astronomy’s observatories look into space in two different ways. Cerro Tololo Inter-American Observatory (CTIO) and Gemini South Observatory use optical telescopes to collect and magnify visible light with mirrors, while the Atacama Large Millimeter/submillimeter Array (ALMA) is a radio telescope comprising 66 networked antennae that collect radio waves emitted by distant astronomical objects.
