3489 Observatory Place, Hyde Park
Founded in 1842, the Cincinnati Observatory houses the oldest fully operational telescope in the nation. On many Friday nights — and some Saturday nights — it hosts public viewings where anyone and everyone (who RSVPs) is welcome to come explore the cosmos with a local astronomer. Listen to a presentation and then partake in a guided stargaze through “a 16-foot long wood and brass refractor first used in 1845.” Weather permitting, you’ll see the moon, planets and stars. If it’s cloudy, you’ll get a tour of the cool historic building. The observatory also occasionally offers interactive Family Astronomy Nights geared toward kids 5-12 years old. Family nights include a tour of the Observatory, a hands-on space-themed activity or craft and a solar viewing if the weather cooperates. And on Tuesdays, Thursdays and Sundays, you can also take part in a daytime history tour, which includes the observatory’s two buildings and two main telescopes, as well as a stop at their out-of-this-world gift shop.
