Support Mount Wilson Observatory

We Need Your Help - Mount Wilson Observatory is privately owned and receives no continuing state or federal support. You can help ensure the continued operation of this science heritage site with your tax deductible gift in one of two ways:

  • Join our Friends of Mount Wilson Observatory organization to receive a variety of member benefits and stay informed on the latest scientific and other activities from the mountain.
  • Contribute to our Second Century Campaign. As Mount Wilson continues into its second century, a capital campaign is being developed to preserve this great observatory for future generations. The goals of the campaign are four-fold:
    • Restore and preserve the Observatory's historic facilities
    • Preserve Mount Wilson as a site for on-going scientific research
    • Create extensive new on-site facilities to foster public understanding of the Mount Wilson heritage and its continuing role in contemporary astronomy
    • Launch on-site and internet-based outreach programs that capitalize on the Mount Wilson tradition to inspire a new generation of scientists.
    The major element of the Second Century Campaign is a wonderful new Visitor Center that will transform Mount Wilson into an important Southern California destination. You can support this campaign directly with your tax deductible donation to the Mount Wilson Institute.

Your support is deeply appreciated and essential to the preservation of this world-class treasure of science and engineering.
