Caltech Events

This March, discover how Caltech researchers are using AI to sharpen scientific insight—from designing AI systems to guide sustainability decisions to combining AI and physics to reveal hidden parts of the universe. More: caltech.short.gy/TW-March-2026

@CaltechAstro returns to Death Valley National Park for the 2026 Dark Sky Festival. From a keynote on the Deep Synoptic Array to Astronomy on Tap and astrophysicist Q&As, explore the full weekend lineup: nps.gov/deva/planyourv…

This February, experience curiosity in action with Caltech Public Events: a Watson Lecture on sustainable battery chemistries, a conversation with alumni on the state of AI, an architectural tour of Caltech, and more: caltech.short.gy/TW-February-20…

As the year draws to a close, we’re reflecting on the public events that brought thousands of community members together on campus over the past twelve months. Thank you for joining us. Check out December Public Events: caltech.short.gy/aGhnK7

Curiosity takes flight this November with Caltech Public Events. From Mars rovers to flying robots, explore discoveries pushing the boundaries of exploration: mailchi.mp/caltech/caltec…

Bananas, quantum science, and the origin of the universe—what do they have in common? They all came up at the first Watson Lecture of the 103rd season, Nick Hutzler shared how his lab studies why our universe has matter but almost no antimatter. Watch now: youtube.com/watch?v=VG4Ovi…

What do we know about planets outside of our solar system? Are there really planets orbiting the nearest star system to ours, Alpha Centauri? On 10/27, head to Dog Haus in Old Town Pasadena to find out at the next Astro on Tap. Learn more: events.caltech.edu/calendar/astro…

On 10/30, experience the real sounds of Mars—wind, dust devils, and seismic rumbles—paired with orchestral melodies created from Red Planet data at Mars Symphony, a free, one-night performance at Caltech. Register: caltech.short.gy/s4CRGP

Powering Earth from space is closer to reality than ever. On 10/27, Movies That Matter presents a free screening and Q&A of Bright Harvest, a film following three Caltech professors and their goal to bring sci-fi into being. Register now: caltech.short.gy/6E8z1U

The big bang should have created equal parts matter and antimatter, but antimatter isn’t freely available in the universe. Caltech physicist Nick Hutzler (BS ’07) is looking for the answer. Find out how at his Watson Lecture on Oct 22: caltech.short.gy/BSw8jO

At @CaltechAstro’s next Stargazing Lecture on 10/3, learn how astronomers discover near-Earth objects and what happens if one poses a threat to Earth. In person and online: caltech.short.gy/QRVlw0

9/25: @CaltechAlumni hosts Techer Live: Future Prospects for American Science, a conversation with Caltech President Thomas F. Rosenbaum and Science editor-in-chief Holden Thorp on science’s role in the public good. More: events.caltech.edu/calendar/teche…

Beat the heat and cool off with Caltech Public Events on the coast and on campus. Check out our August events: events.caltech.edu/calendar/month…

☀️ Summer is here and so are new ways to explore science with Caltech. Cool off with events by the coast or join us on campus for a quantum event for kids or a talk on how solar systems form. July events: events.caltech.edu/calendar/month…

How did our Solar System form over the last 5 billion years? How does our Solar System differ from the thousands of other planetary systems we have discovered around other stars? Join us for a 30-minute public lecture on July 25, followed by telescopes: outreach.astro.caltech.edu

Celebrate Caltech’s newest alumni at our 131st Commencement this Friday! And use #Caltech2025 all week to send a celebratory message to our graduates. Watch here: commencement.caltech.edu/watch
