It’s been just over a decade since scientists made the first confirmed detection of a gravitational wave—subtle ripples in the fabric of space-time predicted by Einstein. These waves have opened an entirely new window onto the Universe, revealing phenomena that were once invisible to traditional astronomy. In this class, we’ll explore how gravitational waves are detected, what they’ve taught us about their extraordinary sources, and how this emerging field is reshaping the future of astrophysics.

Class level: Introductory - This class is recommended for guests of any background. Classes will be held in Mitchel (smaller) building.

Tickets: Non-members - $25/class, Members - $20/class, Student (with valid ID) - $10/class

Weekly Public Program

Astronomy Evening at the Cincinnati Observatory is the perfect program to get acquainted with all of the offerings of your local observatory. Located in picturesque Mount Lookout on the East Side of Cincinnati, the Cincinnati Observatory is the oldest one of its kind in the country that still uses its original telescope from 1845, and now you too will get to participate.

This 90 minute long, family-friendly program features an Astronomy themed presentation on the different things you can experience in the night sky. Tours of our historic buildings and viewing through our telescope takes place during the second part of the evening (weather permitting).

Tickets: $15/adult, $7/child, FREE For Members.  

Reservations required.  Space is limited.

While much scientific research is conducted by professional scientists, there are countless opportunities for everyday citizens to contribute to cutting-edge discoveries. In astronomy, the flood of data from modern survey telescopes has created a growing need for many eyes and minds to help analyze and understand what we see in the universe. In this class, you’ll explore a variety of astronomical citizen science projects and learn how you can participate—no advanced degree required. Discover how your curiosity and time can help advance real research and contribute to our understanding of the cosmos.

It’s easy to assume that the brightest stars in the night sky are the closest to Earth—but in astronomy, appearances can be deceiving. Measuring distance has long been one of the field’s greatest challenges, yet astronomers have assembled a remarkable “distance ladder” that extends from our cosmic backyard to the very edge of the observable Universe. In this class, we’ll explore how astronomers measure distance, from bouncing lasers off the Moon to using stars and galaxies to probe the largest scales of the cosmos.

Class level: Intermediate - This class is recommended for guests with some science and mathematics background.

Our nearest celestial neighbor is often taken for granted, yet it is one of the most fascinating and unique worlds in the Solar System. The Moon is the only place beyond Earth ever visited by humans—and soon, we may return. From how the Moon formed and what lies beneath its surface to how it shapes life on Earth and future plans for lunar exploration, this class takes an up-close look at the Moon as both a scientific mystery and humanity’s next destination.
