Springfield Planetarium

The Springfield Planetarium is a planetarium located in Springfield. The Planetarium's moon exhibit has the words "El Barto was here" carved into it with a laser.

History
The planetarium is one of many locations photographed and listed under "Places El Barto has struck". It is part of the crime file Chief Wiggum had compiled on El Barto.

The Simpson family goes to the planetarium, and Homer weighs himself on a scale, shouting for weighing only 182 lb, but Marge informs him that's only his weight on the moon, and he worriedly shouts.
