The Science Complex at Sacramento State

Encouraging Discovery, Inspiring Innovation, Advancing Knowledge

The Ernest E. Tschannen Science Complex, opening on the Sacramento State campus in Fall 2019, is an ambitious project that, when completed, will put the University’s students in position to tackle worldwide challenges such as climate change and healthy aging – as well as issues we can’t yet imagine.

It will be a hub of discovery, equipped to reach far beyond earthly issues and limits. Looking deep into space and projecting fascinating images to a wide-eyed community, the Tschannen Science Complex will have as its centerpiece a Planetarium and Observatory, windows into the cosmos unlike anything the region has seen.

The Science Complex project features:

  • Science Complex Plaza: Directly across from the vibrant University Union, this living laboratory will have ample seating areas and will be a central meeting space.
  • Planetarium: This 2,500-square-foot dome and its digitally immersive environment will be a destination for students, schoolchildren, and the public.
  • Observatory: With a retractable roof and two telescopes, this companion to the Planetarium will offer prime viewing of the night sky. 
  • Green Terrace: A grass-covered room will provide insulation, and capture and filter stormwater runoff before it enters the American River.

Help us build the new hub for science innovation

The California State University system has committed $71 million in funding toward the $91 million Science Complex facility. But it is not enough to equip the spaces that students need to become the innovative next generation of trailblazers.

Innovative and important projects require help and support from people like you and Ernest E. Tschannen, whose leadership in philanthropy is commemorated in the facility’s name. Construction continues on the Tschannen Science Complex and its Planetarium and Observatory, projects that will mark a new era in science education in Sacramento. The University is seeking private financial support for these projects to fund essential equipment, furnish guest areas, and provide ongoing operating funds.
