September 2021

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, running through October 9. There are no shows Labor Day weekend, September 3-4.

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 will explore the 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, ISU students with ID, 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.

Cash and checks only. Seating is limited and available on a first-come, first-served basis.

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.

Additionally, the Illinois State University Planetarium is pleased to offer The Stars Tonight on September 11 at 3:30 PM. This program is free and open to all. Seating is limited, so please arrive early.

The Stars Tonight explores the planets, bright stars, and constellations visible in the summer sky from Central Illinois. This live planetarium program compliments a free outdoor stargazing session that evening, hosted by the Twin City Amateur Astronomers.

The stargazing will be at the Sugar Grove Nature Center, in Funks Grove, Illinois. A brief astronomical kicks off the evening at 7:30 PM, with the stargazing to follow – weather permitting. There is no rain date. For more information regarding this outdoor stargazing session please visit the TCAA’s web site at Twin City Amateur Astronomers.
