Event Description

The ISU Planetarium is open and we’re thrilled to welcome you back to our dome!  In celebration, we have a great new show for you.  Journey to three world-class observatories in Big Astronomy: People, Places, Discoveries.  Show times are Fridays at 7:30 PM and Saturdays at 2 PM and 7:30 PM, beginning August 13.

This full-dome planetarium show explores Chile’s rugged Andes Mountains and arid Atacama Desert — remote, extreme regions that offer perfect conditions for astronomical research.  There, visit the Cerro Tololo Inter-American Observatory (CTIO) and Gemini South Observatory, which use optical telescopes to collect and magnify visible light with giant mirrors.  Then, trek to the Atacama Large Millimeter/Submillimeter Array (ALMA), a radio telescope with sixty-six networked antennae that collect radio waves from deep space.  Along the way, you’ll meet an inspiring cast of astronomers, engineers, technicians, and support staff who keep these incredible telescopes running.

After each program, we point out highlights found in the current evening sky; including the bright stars, constellations, and planets visible from Central Illinois.

Admission to the ISU Planetarium is $5 for adults, $4 for children ages 5-12 and seniors, and $3.00 for children ages 3-4.  Tickets are available in the Planetarium Gift Shop, next to the Planetarium, beginning 20 minutes before each show.

The ISU Planetarium is located under the white domed roof at the eastern end of Felmley Hall of Science Annex.  Felmley Hall is located on the northeast corner of the ISU campus at the intersection of College Avenue and School Street.  

Free parking for the Planetarium’s weekend programs is available a short distance from the ISU Planetarium in the University’s red tag F-67 parking lot, located on the east side of School Street.  

Following the latest CDC guidance and Illinois State University policy, face coverings are required in all University public indoor spaces.  This includes the ISU Planetarium.
