Announcing Moonfest!

Welcome to moonfest! The University of Arizona celebrates the 50th Anniversary of the landmark Apollo 11 moon landing this July with special events and exhibits. With so much going on, we decided to give the collection of events a name: moonfest!
50 years ago, on July 20, 1969, American astronaut Neil Armstrong took the first step onto the surface of the Moon. It was a moment that forever changed our understanding of who we are, where we are, and what we can achieve.
It was also the beginning of a golden age of planetary science. The University of Arizona has been there every step of the way, from the moon landing to the exploration of all the planets in our solar system. Celebrate the 50th Anniversary of the Apollo 11 Moon Landing at the UA’s moonfest events. Go to for more information.

Tumamoc Tour App

With each step, hear about the others who that have made the same trek over time. Discover the plants and animals that tell us about where we’ve been and where we’re going. And experience features like an augmented reality reconstruction of the village that once stood on top of the hill 2,500 years ago.
The Tumamoc Tour is divided into six sections that correspond to a distinct portion of the road, each punctuated with music by the band Calexico and paced to coincide with your walk up and down the Hill.

2019 UA Science Lecture Series

We hold scientists in high regard as truth seekers and knowledge keepers. Their findings and research are independently checked, verified, proven and subjected to peer review. These processes and methods are applied rigorously and form a common framework for scientific inquiry. In this series of six lectures, scientists from across disciplines at the College of Science shed light on how the scientific community works together to build consensus from evidence, mediates differences of opinion in the face of debate and ultimately establishes theory – scientific truth that grows and evolves over time.

2018 Lecture Series

In our automated lives, we generate and interact with unprecedented amounts of data. This sea of information is constantly searched, catalogued, analyzed and referenced by machines with the ability to uncover patterns unseen by their human creators. These new insights have far reaching implications for our society. From our everyday presence online, to scientists sequencing billions of genes or cataloging billions of stars, to cars that drive themselves – this series of six lectures will explore how the confluence of humans, data and machines extends beyond science – raising new philosophical and ethical questions.

Community Science Scholars

The College of Science is pleased to announce the Community Science Scholars Program. This new initiative allows members of the local community to audit science classes at the UA for a reduced tuition rate. The goals are to increase the College’s engagement with the local community and give lifelong learners a chance to learn from our world-class science faculty. Over two dozen classes are offered this Fall semester. Classes span ten departments within the College of Science, from life and physical sciences to mathematics. Examples include Golden Age of Planetary Exploration, Frontiers of Brain Science, Foundations of Biochemistry, Historical Geology, Bioinformatics Seminar, and Astronomy and the Arts. Instructors include award-winning teachers, University Distinguished Professors, and Department Heads.

2017 Lecture Series

Our intuitive understanding of reality comes from what we see and experience, but modern physics tells us that our world is actually stranger than the one we see, hear and touch every day. At extremes of scale, speed and time, our perceptions of the world prove hard to reconcile with established physical law. Here, at the cutting edge of physics where we attempt to reconcile the bizarre domain of quantum mechanics with the cosmic vastness of relativity, we must increasingly rely on new ways of thinking, seeing and experimenting to probe the principles which underlie everything. Join us as five University of Arizona physicists explain their role as pioneers rethinking the rules of reality.

2016 Lecture Series

Climate change and its impacts are no longer merely abstract projections for the future. Instead, they are on-going and growing challenges for both humans and many of the natural systems upon which we depend. Globally, changes in the oceans, ice sheets and atmosphere provide clear fingerprints of the human causes, but also important lessons for society to learn as we seek solutions. Even more than when the UA Science Lecture Series originally turned to climate change a decade ago, the Southwest is dealing with a looming water crisis, unprecedented severe wildfire risk, emerging human health concerns and much more. Scholars and the public alike need to brainstorm and work to ensure a resilient and vibrant future for the Southwest and the planet.

2015 Lecture Series

The 2015 UA Science Lecture Series explores our Universe at molecular, biological, planetary and cosmic scales to ask 'What is life?' and how do we recognize it? Life as we know it produces complex order. Earth's many life forms are diverse and continually changing through birth, growth, and evolution. To understand life in the Universe we ask: What environments produce life and which attributes make something alive? How does life change? Is there life in our Solar System, or on one of countless exoplanets? Is there a connection between life on Earth and life elsewhere? Or are we alone?

2014 Lecture Series

The astonishingly complex human brain is the product of hundreds of millions of years of evolution. Layered upon its ancestral core of ancient molecules and neural circuits, which have comparable functions in other animals, new structures have evolved that expand the capacity of the human brain to flexibly process information and to elaborate complex behaviors.
