Dean Regas: Your Astronomer

Featured in the New York Times

Dean has been the Astronomer for the Cincinnati Observatory since 2000. He is a renowned educator, author, national popularizer of astronomy and an expert in observational astronomy.

Dean is the co-host of Star Gazers, a new twist on an iconic backyard astronomy program which airs on over 100 PBS stations around the world. He is the author of three books "Facts From Space!""100 Things to See in the Night Sky", and 100 Things to See in the Southern Night Sky. Dean is a Contributing Editor to Sky and Telescope Magazine and a contributor to Astronomy Magazine, where he won 2008 “Out-of-this-World” Award for astronomy education.  Dean has written over 120 astronomy articles for the Cincinnati Enquirer, blogged for the Huffington Post and is regularly featured on television and radio.  Since 2012 Dean has been a frequent guest on National Public Radio’s Science Friday with Ira Flatow, and this year he began an astronomy podcast with Anna Hehman called "Looking Up!"  

At the Cincinnati Observatory, he has developed his skills as a dynamic writer and public speaker who brings the complicated field of astronomy down to Earth for students of all ages.

100 Things to See in the Night Sky

Dean shares his handy field guide for the best stargazing experience whether in your own back yard, camping, or travelling—including information showing you which planets, constellations, stars, and manmade objects you can see with a telescope, or just your naked eye!

Each object is presented as a separate entry, with background information on the makeup, appearance, and history of the object, along with easy-to-follow instructions on how to find it. For astronomy and space fans of all ages, this guide helps you explore the galaxy and see the stars—while keeping your feet on the ground.

Facts From Space!

From Super-Secret Spacecraft to Volcanoes in Outer Space, Extraterrestrial Facts to Blow Your Mind!

Dean's first book will take you from the Earth to the edge of the universe and back.

How did turtles, flies, meal worms, and bacteria become the first living things to go the far side of the Moon?  How do you go to the bathroom in zero-gravity?  Where should we look for aliens? You will see a Martian sunset, swirl in Jupiter’s Great Red Spot, skim the corona of the Sun, and fall into a black hole.
