See Mercury and Venus

At the Cincinnati Observatory
Sunday March 18 from 7:30-8:30pm

On the evening of March 18 you will see the slimmest crescent Moon in the western sky.  And joining the Moon that night, looking like two tiny “stars,” will be the planets Mercury and Venus.  All three objects will be lined up perfectly, and we want to show them to you.    

See Mercury and Venus includes viewing of the Moon and planets with telescopes (weather permitting) and tours of the older telescope that was completed in 1845 (if cloudy or raining). 

Arrive right at 7:30pm for the best chance to see the planets.

Admission: $5 per person, Free for Observatory Members

No reservations are required.
For more information, please call 513-321-5186.

Join us on March 19 at 7pm to hear a talk from Dr. David Rutishauser, a Cincinnati native and 1988 graduate of Purcell Marian High School who has worked as an engineer for NASA for the past 17 years.

He'll be speaking about what it’s like to work at NASA and engineering in space!

Seating is limited.

Blue Moon

At the Cincinnati Observatory
Saturday March 31 from 8-10pm

When you have two full moons in a calendar month, the second one is nicknamed a “Blue Moon.”  The Moon doesn’t actually turn a bluish shade, but it will give you a great excuse to bring your friends and family to the Observatory to watch a Moon-rise and star gaze as well.

Blue Moon includes tours of the two Observatory buildings and viewing of the Moon and stars through the telescopes (weather permitting).  Bring blankets, lawn chairs, and warm clothes and have a nice evening outside under the Moon. 

Moonrise is at 8:22pm

Admission is $10/adult, $5/kid, Free for Observatory Members

No reservations are required.  Great for all ages.
For more information, please call 513-321-5186.

Late Night Date Night

Saturday April 14, from 10:30pm-Midnight
Friday April 27, from 10:30-Midnight

Looking for a romantic Saturday night out under the stars? See what the Observatory is like after hours. You'll get to use the oldest big telescope in the U.S. to view astronomical objects that are not visible until late at night (weather permitting). Get a sneak preview of the next season’s planets and stars a month or two ahead of everyone else.

For adults only. If the weather does not permit viewing, we’ll have fun showing you around the universe and behind the scenes at the Observatory.
