Ball State astronomers and the Muncie Astronomy Club have created a program to challenge your concepts about what is the most beautiful sight in the world.

Using photographs of celestial hot spots, the astronomers will offer glimpses into some of the most beautiful sights in this galaxy — and beyond, says Ron Kaitchuck, planetarium director. The program, the last installment in "A Visitor's Guide to the Universe," will be at 7:30 p.m. April 13-14 and 20-21 at Ball State's planetarium.

During the 40-minute program, visitors will see photographs taken by Ball State astronomers, members of the Muncie Astronomy Club and major observatories.

Planetarium shows are free and open to the public. No tickets are required, but seating is limited. Doors will open 20 minutes before show time, and no one will be admitted after the program begins.

The program is suitable for children who are at least 8. Children who are 12 or younger must be accompanied by an adult.

Weather permitting, the campus observatory will be open after the presentation. The observatory is not heated so patrons are urged to dress accordingly.

The planetarium is off Riverside Avenue in the southeast corner of Cooper Science Complex. Parking is available on the west end of the building and along Riverside Avenue.
