With the star ball banished, the sky's the limit now for the Gottlieb Planetarium. A new 360-degree and 3-D projection system now operating in the funny-shaped building next to Union Station is hoped to bring back audiences and send them to the moon and beyond. And the best part is that the system was assembled by local talent at a fraction - no, a fraction of a fraction - of what it would have cost to purchase from a planetarium vendor.
