Friends of Steward Observatory

Welcome to Friends of Steward Observatory.  

Nearly 100 years ago, Lavinia Steward gave $60,000 to the founder of the department of physics and astronomy, Andrew Ellicott Douglass. That gift built the Steward Observatory and launched a department that leads the field in teaching and discovery, manufacturing and research. In February, 2018 we celebrated the100 year anniversary as a campus department. 

As a Friend of Steward Observatory your donation will help support Astronomy and enhance the education, research and environment of our Astronomy department and Steward Observatory. 

Friends of Steward Observatory funds go to:

  • Student Scholarships
  • Student attendance at professional conferences
  • Support of summer work projects
  • Astronomy Club activities
  • Gender Minorities group (formerly Tucson Women in Astronomy)
  • Graduate Council group
  • Special projects


The University of Arizona's Department of Astronomy and Steward Observatory is a world-renowned institution at the forefront of modern astronomy. We sustain one of the largest and innovative communities of researchers and students on the planet. Developing the expertise and early careers of undergraduate and graduate students is an essential component of building and sustaining our strong and diverse science community. The Department of Astronomy offers academic programs, including a Bachelor of Science in Astronomy and a Ph.D. in Astronomy and Astrophysics. Steward Observatory is the research arm of the astronomy program and includes the Richard F. Caris Mirror Lab, Mount Lemmon SkyCenter, along with management responsibilities of 25 telescopes located on 8 sites worldwide. 

FoSO members will receive invitations to special "space science" events throughout the year.

Donations are tax deductible. Your support will make a difference.

We hope you have an opportunity to join us as we explore the cosmos.

"If there is anything that can bind the heavenly mind of a man to this dreary exile of our earthly home and can reconcile us with our fate so that one can enjoy living, then it is verily the enjoyment of the mathematical sciences and astronomy." -Johannes Kepler
