Public Events


Saturday August 27 from 7:30-9pm

You've probably seen them in the evening: two suspiciously bright lights in the western sky. What are they? Planes? UFOs? No, they're Venus and Jupiter and they're heading for a dramatic conjunction on the 27th.

Join us at the Cincinnati Observatory to see these two bright night lights right next to each other.  We will set up telescopes to help view this special event and also lead views of Saturn through the 1845 telescope (weather permitting). 

No reservations needed.  Drop-ins welcome.  Great for all ages.

Cost: $5 per person.  Free for Observatory members.
