Support Carnegie Astronomy
A Tradition of Support
From the early 20th century,
when Los Angeles
businessman John Hooker donated the funds for
the 100" telescope on Mount Wilson, to today,
motivated individuals have generously supported the
research programs of the Carnegie Observatories.
The priorities of those who give encompass:
• the past—such as preserving Carnegie's historic collection of 250,000 glass plate negatives of celestial objects
• the present—such as ensuring that that today’s modern telescopes are equipped with the best, most sensitive instruments and cameras, and
• the future — most notably focused on leading the world in building the next generation of ground-based optical telescopes.
Our benefactors continue Andrew Carnegie’s legacy of private philanthropy in support of scientific discovery for the public good.
Giving to the Observatories

Contributors to the Carnegie Observatories join a team of outstanding scientists tackling some of the most intriguing and important questions about stars, galaxies, supernovae, black holes, and the distant origins of the universe.
• Make an online gift via credit card or Paypal account
You can designate your gift to the Observatories general support fund (labeled "The Carnegie Fund | The Observatories"), to Carnegie's share of the Magellan telescope project, or to Carnegie's share of the design and construction of the Giant Magellan Telescope.
Gifts to these designated funds underwrite almost all aspects of our astronomical research.
