Mr. President, I rise today to recognize a jewel of American science and a California landmark: the Lick Observatory on Mount Hamilton. June 7, 2026, marked the 150th anniversary of the Act of Congress that reserved land for the construction of this observatory that has been the site of countless scientific discoveries.
1874 endowment of $700,000, valued at over $1 billion today, laid the foundation for what is now the Lick Observatory, Lick Observatory was the world's first permanently staffed mountaintop observatory. When it opened in 1888, it housed the 36-inch Great Refractor, then the largest telescope on Earth, cementing California as an early epicenter of astronomical research.
breakthroughs. In 1892, its researchers achieved the first photographic discovery of a comet and identified a fifth moon of Jupiter. A 1922 Lick Observatory eclipse expedition provided the empirical confirmation of Einstein's general theory of relativity, a moment that fundamentally shifted our understanding of the physical world.
into the 21st century. In the 1990s, Lick Observatory pioneered adaptive optics to pierce through atmospheric distortion and was at the forefront of the search for exoplanets. Its robotic telescopes have monitored over 1,000 supernovae, which provided crucial data revealing the acceleration of the universe's expansion, a discovery honored with the 2011 Nobel Prize in Physics.
Lick Observatory remains a vital keystone for education. It serves nine UC campuses and two national laboratories and partners with California's State universities and community colleges, training the next generation of scientists while inspiring tens of thousands of visitors through its outreach programs.
spirit and our enduring commitment to discovery. I ask my colleagues to join me in commemorating this 150th anniversary and honoring the observatory for its extraordinary contributions to humanity's understanding of the cosmos.
