If you're looking for something free, fun and educational to do with the kids, take in a show at the Gene Roddenberry Planetarium this month. And -- bonus! -- it's a cheap, entertaining way to beat the July heat and humidity.

Monday through Thursday, July 16-19, Monday through Wednesday, July 23-25, and Monday and Tuesday, July 30, 31, the planetarium will be hosting 3 different programs (see below) for families and individuals interested in learning about our planet and the solar system.

• 11 a.m. - "Perfect Little Planet"
• 2 p.m. - "Earth, Moon & Sun"
• 4 p.m. - "A Starry Tale"

The live portion of the shows on Wednesdays will be presented in Spanish. The program itself, however, will still be in English.

This year for the first time, the majority of tickets will only be available online. Eighty of the 120 available seats will be distributed exclusively online. The remaining 40 seats will be made available one hour before each presentation on a first come first serve basis. Because the programs are free and seating is limited, it's recommended you reserve your seats in advance.

Online reservations can be made beginning 4 days before the date of the show. You'll find the link to do that here.
